Add Diaspora chat system w/ fixes [MORE]

[awilliamson]

• Make transparent messages either clientside or web-serverside ( Fading on chat close etc )
• Work on GWEN Skin that it uses - Eg Isolate the skin so that any changes only effect the Chat.
• Change Teams to use Player Manager - And use appropriate race colors
• Fix scrolling to scroll as normal w/o visible bars
• Change location of elements to improve visuals
• Location of text input either moved, or length of the chat box extended downwards
• Change width of chatbox when scrollbars show up
• Move / Align whole chatbox to match padding of normal HUD elements
• Change size of chatbox to be slightly smaller and possibly scale to UI size.
• Fix the 'x' button not calling close chat properly
• Fix the team tab to show messages from team automatically without chat refresh
• Fading from ALL chat applied to TEAM chat messages on that tab.
• Color the [ TEAM ] Labels appropriate to team
• Add indicator to let user know when they are typing to ALL or just TEAM
• Prevent team say concmd as that uses teams and not player manager
• Try to get text input background transparent ( use draw if required! )
• Add very transparent dark grey background for chat to improve visability ( on chat open or all time ? )
• NEW: Highlight backdrop will show even after text disappears
• NEW: Text can still disappear/fade out when you have chat open typing more messages :/

Note that right now all of the chat files are on my personal fork because awilliamson(radon) doesn't want it in the repo til its perfect, hence making this a bit confusing.

[LtBrandon]

All done, except I haven't changed anything in the GWEN skin as I have no idea what you would want.

[awilliamson]

Not closed as it actually isn't added, please don't confuse your fork with the official repo

[awilliamson]

Chat is now added in the official repo, original issue updated with things still left to do.

Instead of having a grey background, make the text have a black shadow. That will improve readability a lot.

[awilliamson]

It currently does that, but depending on background readability actually decreases! So I don't know, a bit of fiddling will be required. Generally just any background based solution to improve readability is required, whether that be a text shadow or full back shadow.
