[handsome_feng]

I think the new version of ukui-panel just has bug fixes.

The changelog:
  * Fix the errors when click "Customize icons appear on the taskbar".
    (LP: #1755663)
  * Adjust the size of a new panel and other added icons. (LP: #1755690)
  * Fix the errors when check the "Lock the launcher". (LP: #1755684)
  * Get color value from ukui-blue theme and change the taskbar
    background settings.
  * Fix the error 'missing action Remove'
  * Fix the error 'g_signal_handlers_block_matched'
  * Fix the wrong icon size of window-list after resize panel.
  * Fix the segment error when set the hide/show in settings.
  * Remove some useless settings.

It has been tested and stored in the PPA:

Seeing the changes it's not clear if this needs an FFe in the end or not. I do see that some strings have been added to the .po file, but I don't see if those come from modifications of the source in this version or not. All in all, the new version seems sane from the release POV so just in case: FFe approved.
