Fixes to Spanish and Catalan translations.
Merge branch 'stable'
Use wxPLURAL with a translatable string containing a plural.
Make file selector strings translations less error prone.

Segregate translatable messages and file extensions in strings given to
wxFileSelector. This is to avoid possible typos in translations changing
the behavior of the application, and to save the translators some
trouble with long and cryptic messages.
Use consistent file types naming.

Use the same, less obscure, names for file types with wxFileSelector
that are already used for filetype information for the OS.

Also standardize on the correct (for both OS X and Windows) spelling,
with title case.
Fix next/prev menu entries.

Should be "translation", not "message" (where did that come from?!).
Sort poedit.pot by file locations, not by msgid.

Sort POT by file locations, because sorting by msgid makes it hard for
the translator to figure out which strings belong to the same context
and which do not.
Merge pull request #77 from lanurmi/sort-files-not-msgids

Fix missing pluralization in VerifyFileCharset.

Add Group By Context sorting option.

Add an option to group messages by context to the View menu.  If the
catalog uses contexts heavily, this makes it easier to translate the
strings, as related texts are put together.
Increase version to 1.7beta1.

Fix UTF8 source file BOM for Visual Studio.

...again.
Rename "Parsers" to "Extractors".

The new term better describes what they do - extract translations from
source code.
Don't use WX_DEFINE_LIST/OBJARRAY.

Replace them with appropriate standard containers.
