Install Blue Wave GTK3 themes on Ubuntu/Linux Mint

Install Blue Wave GTK3 three themes on Ubuntu 12.04 Precise Pangolin/ Ubuntu 11.10 Oneiric/Linux Mint

Author Created this theme using Ubuntu's Ambiance GTK2/GTK3 as a building block.
The purpose of this theme was to make something that was easy to read, integrated well in both gnome-shell and ubuntu unity desktop, and looks seamless between gtk2 and gtk3 (still working on that).
Also included is a gnome-shell theme, but it is far off from completion and probably shouldn't be used on a production desktop.

Changes for Version 1.4 Blue Wave:

• Changed GTK3 default and toolbar buttons to give them the effect of pressing them in when active.
• Fixed the treeview column colors. (now there are none just white to match canvas)
• Added light borders to notebook frames, tabs, fixed column headers.
• Few other minor tweaks.
• Gnome Shell Changes
• Changed a lot of stuff to make the theme fit with overall appearance of the GTK+ themes.
