MHX importer: Added support for loading and saving mcp files, which is a simplified format for storing poses used by MH. 

Mhx importer: Only panels relevant to the active rig are displayed. Other panels, e.g. the expression panel for a character without expressions, or the FK/IK switch panel for a non-mhx rig, are hidden.

MHX importer: Tested with Blender 2.68a. Better FK/IK snapping, which however only works with mhx rig in MH svn.

The rig will not be imported correctly unless Auto Run Python Scripts is turned on. Therefore an comprehensible error is raised if this is not the case.

Added additional check for None rig.

MHX importer: Support for rigify rig updated to be compatible with Rigify plugin for Blender 2.67 RC1.

make addons blender versions consistent

MHX importer: the idea to use rna props did not pan out, because it lead to errors when a saved blend file with an mh character was reloaded. Fixed that.

Added support for new visemes and removed export of old faceshapes. Also fixed MH alpha 7 compatibility.
