STORM-535 FIXED PLEASE allow adjustable transparency of "Nearby Chat" window, Chat History and Chat "Toasts" in Viewer 2.0!

- Added to the settings.xml values of transparency for active and inactive floaters

- Added three members to the LLFloater. These members store current transparency of floater, transparency of active and inactive floaters.

- Added callbacks that update transparency value of active and inactive floater. Also in these callbacks value of current floater transparency updated.

- In panel preferences advanced added two spinners: transparency of active floaters and inactive ones. See screenshot.
