Feature Request: Add LiruResizeRootWithScreen to prevent ui getting messed up when the window is resized

This is not complete, and it should only be used if you know what you're getting into.
Maximum bandwidth is apparently 10000 on SL Viewer, match that.
Add Render muted avatars check to System->Security & Privacy Preferences

Redefaulted LiruLegacyDisplayMuteds to false due to (at least) two alpha testers noticing it and wanting it back how it is in the current release (since 1.7.0).
True was to get back to the old ways of v1, but it's okay to be false by default, better now since it's exposed.

Also irrelevant tiny voice cleanup from Spatters.
Em Dash wants build tools to focus properly when the build button is clicked.

If the world is in focus and build button is pressed without the build floater open, don't bother focusing.
If a floater is in focus and build button is pressed without the build floater open, focus the build floater
If the build floater is in the background and the button is pressed, focus the build floater.
If the build floater is in focus and the button is pressed, close the build floater.
If the build floater is  not in focus but nothing else is, close the build floater.
