Applied patches from Hex-Rays:

- added MakeYword
- wrap obsolete IDA API functions too, so that old scripts continue to work
- added debugger trace related functions in idc.py
BUGFIX: IDAPython would fail with a cryptic error message if there was no free space on the current disk
BUGFIX: site-packages directory was missing from sys.path
BUGFIX: functions for working with additional lines (LineA/LineB etc) were broken
BUGFIX: GetFixup* functions from idc.py were broken
BUGFIX: IDA could not start if another python27.dll was present in PATH and importing site.py for that Python installation failed
BUGFIX: SaveBase() was broken

BUGFIX: Dbg/Idp hooks automatically unhook when hook object is not referenced anymore

note: these patches are already applied in IDAPython that comes with IDA Pro 6.4
