Update Spanish translation
Show details about uncaught NSExceptions.

Previously the code only handled C++ exceptions and reported only a
generic error for uncaught NSExceptions.

Take advantage of 64bit Obj-C runtime's interoperability of Obj-C and
C++ exceptions and handle NSException too.

See #90.
Don't use REKit on OS X 10.7.

LanguageCtrl's case-insensitive auto-competition requires REKit code,
but that throws an exception on 10.7.  Rather than trying to fix the
rather low-level REKit code to work on 10.7, give up on this small
enhancement - it's not worth the effort when the next version of Poedit
will almost certainly require 10.8+ anyway.

Fixes #90.
OS X: Fix undo-related exceptions.

Reset the undo manager's state when going to another translation.
Without this, it was possible to apply undo operations after the
underlying text changed.

"Proper" solution would be to have global undo, not just local to the
current text, but that's for a future version.
Fix non-OSX compilation after 0136b92.
Fix Persian translation's plural forms.

Some random, invalid string was in there.
Rename translation: fa_IR->fa and af_ZA->af.

These languages aren't really country-specific variants, so just use the base name.
Add Crowdin configuration file.

Manage translations on Crowdin.net.
Merge pull request #88 from Fitoschido/patch-1

Update Spanish translation.
Don't try to get FindFrame for NULL list.
Don't show TM translation progress window for empty catalogs.

No point in showing progress for count=0.
Enable localization of Info.plist on OS X.

So far only two keys - names of translation files - are localized.

Also add to crowdin.yaml.
Update LetsMove.

The important part is modern naming of translation directories.
Upload LetsMove's MoveApplication.strings to Crowdin.
Merge branch 'use-crowdin' into stable
Better handle faux-fatal msgfmt errors.

Some errors reported as fatal by msgfmt without -c are in fact no fatal
and don't prevent MO file creation.

Moreover, msgfmt can return no-zero exit code and *still* produce a MO
file on output.  Watch for this case and report it truthfully.
