Guake 0.8.4

After the installation of Ubuntu 16.04, I found that the corresponding Guake is like Gnome Terminal.

1. The current tab is colored with pink.

2. Support hotkey to switch tabs.

If we still use the old versions of Ubuntu Release, we can get the latest the release with following links:

PS: after installation, we have to restart the programme!
