pginstaller - pginst: Fix a couple of error messages that were

Log Message:
-----------
Fix a couple of error messages that were duplicated because of different spelling.

Add tooltips to translations. Add folder names in start menu to translations. Remove incorrect translation of bitmap filenames.

Fix incorrect double-escaping of backslashes in C strings when translating.

Add tool to verify parameter count and types of translated strings.

Add missing parameters to some translation strings in de and pt_br translations.

Sync up translations.

Add explicit check for cygwin in the system PATH and recommend turning it off. If a cygwin tcl84.dll (and possibly others) are loaded they can cause both lockups and crashes, both in the installer and in the backend.
