- make ToolSettings.mesh_selection_mode into an array of 3 bools rather then an enum since multiple can be set at once.

- ToolSettings had its id.data set to NULL when taken directly from the context (causing a crash in cases)
- menu for changing vert/edge/face selection now a python menu, removed operator.
- wm.context_set_value(), would really prefer not to have this since it evaluates the value as a python expression however there are no ways to define arrays in PyOperators
