Removed "Clear Text" context menu from roll down dialog
Fixed "Clear Text" context menu in Info Dialog (renamed to "Clear Messages" in the process)

Shrunk the Message drop down dialog a bit.
Made the Message drop down dialog slightly transparent.

Right-click menu works cleaner.
Coloring of output text is correct.
Output text now handles all severities of messages.

Anton and I noticed that the message view stops autoscrolling properly
sometimes when there's a high frequency of arriving messages. This
should fix that problem.
