* Ported mesh editmode 'select random' from tuhopuu by popular request

Description:
Mesh editmode header/toolbox: Select -> Random...

Randomly selects a user-set percentage of vertices, adding to the current selection.

* Modified some menu entries to be consistent with the guidelines doc.

* Added 'Align Active Camera to View' in 3D View menu
