Update Russian and Ukranian translations.

Remove stray double-quote marks.
Move alt_sends strings to their correct relative positon in the file.
(Which doesn't affect how they work, but makes maintaining the
translation easier.)

Remove execute bits that accidentally got set on the file permissions.

Turn off execute bit for resource files.

This bit gets set when files come from MS-DOS file systems.

There's no reason to have it set.
