Forward port of various fixes that were initially only done on the

release23-maint branch:
- Remember the scroll position when rebuilding the browser (as we do far
too often). Fixes #824430.
- Allow for the documentation to be inside PythonIDE as well as in
the Python.app inside the framework (the original location for 2.3).
- Updated version numbers
- In PythonIDE, add the Tools/IDE directory as the second entry in
sys.path in stead of as the first, leaving PythonIDE.app/Contents/Resources
as the first one.
- The code for setting the working directory to $HOME was both incorrect
and in the wrong place, fixed.
- On OSX the default location for IDE scripts is now
$HOME/Library/Python/IDE-Scripts.
