UI Buttons:

* Context now allows pinning a datablock, independent of
  selection.
* Initial ID browse buttons for most buttons tabs.
* Browsing from world to texture now displays world textures
  again, but is a bit of a hack, not sure there is a right
  way to do this.
* There's a button to switch between active materials and
  textures now, only temporary though.
* There's some code to put context part in own region,
  disabled still because it doesn't work that well yet.
