We were not able to handle ~/... type of path configurations and we
crashed with mysterious SSL errors when no file was found at the
configured location. Expand '~' and bomb out with usable error messages
in case such a file does not exist. This will still not protect against
corrupt cacert files but it goes a long way towards user friendliness.

I accidentally added "self" as first parameter to the signal handler
method. Of course it is not called with a class instance, the signal
handler always only receives 2 parameters: the signal number and the
stack frame. So just removing the self fixes things.

Currently the Curses code is broken. Importing offlineimap.ui.Curses
will not succeed due to cyclic imports (threadutils imports ui, but ui
wants threadutils.MultiLock). So Curses cannot be chosen.
Incidentally, the only part in the code that uses "MultiLock" is the
Curses UI, to prevent concurrent access from several threads to the
ui-internal thread list and to IO resources such as the
screen. Fortunately for these purposes we don't need a MultiLock, so we
can do away with that implementation completely. A simple RLock that
allows us to have a thread "own" a lock and makes other threads wanting
access to the resource wait until the owning thread is finished.
The MultiLock implementation looked a bit weird, so simplifying code
here is a good thing, it might well be that we fix some "hangs" that
have been reported (and that would only ever occur with the Curses UI).

Previously, we would spawn child threads for account synchronization
even if we had single-threading enabled. This prevented us from catching
the true location of exceptions, for example. Now, in single-threaded
mode, we perform the account synchronization truely in the main thread
which will ease our debugging.

Earlier we would ignore *ALL* Exceptions that could occur during the
fsyncing of our LocalStatus database. Ignoring all Exceptions is not the
right thing here though. A recent commit improved the situation by
raising at least KeyboardInterrupt Exceptions, but that is still not
optimal.
os.fsync() is available on Unix, and Windows starting in python
2.2.3. so it should always work. If it doesn't, something is wrong.
It has been suggested to only catch EnvironmentError (ie SystemError and
OSError) here, but even those should be thrown. Something *is* wrong if
this fails and we should not ignore it.

Previously we did not catch KeyboardInterrupts explicitly as all of the
code was executed in forked child threads which would never receive
Ctrl-c exceptions. With the upcoming single threaded modus, this code
can be run in the main thread however, so we need to take care of
KeyboardInterrupts explicitly.
This was done wherever we would catch *ALL* exceptions universally and
print out an error message.

The ui.detector class was not really needed and leads to the illusion
that we provide GUI plugins. For the sake of code maintainability we
don't :-).
Rather than having GUI names equivalent to the classes they are in
(which leads to weird names like TTY.TTYUI), this patch allows to give
each GUI an arbitrary string name. GUI names remain still unchanged in
this patch, the default UI when none was configured is TTY.TTYUI.

Previously, we did not check at all the authenticy and validity of
the SSL server we connected to. This is bad as it allows
man-in-the-middle attacks etc. This patch remedies the situation
somewhat.
If we specify a sslcacertfile= setting in the Repository section,
validate the server cert (on python>=2.6 or abort with python<=2.5).
As before, no certificate check is performed without that option.
In the future, the hostname check should be made optional and also
a mutt-lick "accept this certificate forever" thing should be
implemented.

Move the command line option handling from the more manual "getopts"
module to the full fledged "OptionParser". It has the advantage of
e.g. automatically creating the Help text that is shown with the
"-h/--help" option rather than having to hardcode the text and
format the line breaking manually.
Also, do away with the version check when invoking OfflineImap so we
do not have to change the version number in three places when bumping
it.
Rename startup() to run() which sounds more in line what other modules
call their run functions (e.g. Thread.run()).
