v2.242 Browser Client, URL hider (mobile), Better background management

[Glitchless]

In this version we are testing different methods of forcing background action while you are focused on other tabs. We are attempting to use intended methods for background activity before testing ugly hacks.

When changing font colors via the Seer, you will now see the hex color codes for your selections. If you have a dual custom face, you can now let us know and we can manually assign a different font color for each custom face.

On mobile, if you open chat (civil,uncivil,tell,pm,group,clan chat) and don't wish to say anything, you can just hit submit and the text box will go away rather than being stuck open like before.

For mobile, we removed the need to do the sharp upward gesture in order to hide the URL bar, and are using a less intrusive method.
