Fixed bug EXT-4369 ([BSI] Changing image in "Pick" doesn't trigger "Save Pick" button to be active)

* Changed the Save button to react on texture picker commit, not on selection.
* Added an optional "no_commit_on_selection" parameter to LLTextureCtrl
  to commit only when user presses the OK button in the picker or changes
  the texture via DnD, i.e. browsing in the picker doesn't commit.
