Include svn revsion in AddIn Version

This allows the user to easily see which revision of the
AddIn he/she is using.

This is done in a slightly unpleasant way in that it
modifies the AssemblyInfo.cs in place before the build
but this seems to be what all the recommended techniques
also do in MS land.

visual_studio/NativeClientVSAddIn/buildbot_run.py:72: pattern = r'(\[assembly:
AssemblyInformationalVersion\("\d+\.\d+\.).*"\)\]'
I think this regexp should extract the end part too... also, use a non-greedy
match for the part you're replacing:

\("\d+\.\d+\.).*?("\)\])

then sub using \1%s\2

Could also use lookbehind and lookahead assertions here, but maybe that's
overkill.

visual_studio/NativeClientVSAddIn/create_package.py:104: path =
u'\\StringFileInfo\\%04X%04X\\ProductVersion' % (lang, codepage)
needs to be unicode string?
