D54: Added a filepath attribute to the read_homefile operator.

Browse Source 
This attribute allows to open a blend file as an alternative
start-up file. The attribute is only available from python.
This is an example call:

    bpy.ops.wm.read_homefile(filepath='path/to/a/file.blend')

This patch also changes readfile.c to ensure that unintentionally
stored cursor states are not imported from the loaded file.
