[Bug #1545726] Incorrect FSF address in many extension files.

update Python extensions from 90 to 96 dpi.

Extensions. Fix for bug #887539 (Permissions and #! in extension scripts need fixing).

Super duper mega (fun!) commit: replaced encoding=utf-8 with fileencoding=utf-8 in all 1074 Vim modelines. The reason for this is that (a) setting the encoding isn't nice, and (b) Vim 7.3 (with modeline enabled) disallows it and pops up an error whenever you open any file with it ("invalid modeline"). Also corrected five deviant modestrings: * src/ui/widget/dock.cpp and src/ui/widget/dock.h: missing colon at the end * src/ui/dialog/tile.cpp: removed gratuitous second colon at the end * src/helper/units-test.h: removed gratuitous space before a colon * share/extensions/export_gimp_palette.py: missing textwidth=99 That's my geekiest commit yet.

share/extensions/*.py: Wrap ‘e = MyEffect(); e.affect()’ in ‘if __name__ == '__main__':’, to allow use of pychecker.

noop: Add vim modeline for all share/extensions/*.py files that use four-space indentation.

share/extension/*.py: noop: minor whitespace regularizations ahead of adding vim modelines

Attempt fix for Bug #178022 Evidently somewhere between versions 1.3.6 and 2.0 lxml began requiring that parameters passed to the Element.xpath() be keyword arguments (positional arguments had been allowed). Best guess places this at "2.0alpha6 (2007-12-19)" based upon the lxml Changelog. This fix appears to be backward compatible. Please test.
