Build MSBT frames in Lua and drop MikScrollingBattleText.xml

Browse Source 
The XML hand-copied 60 font strings whose anchors were overwritten before
every message. Create the event frame and the three scroll area frames
with CreateFrame/CreateFontString instead, keep the frame object on each
scroll area rather than its global name, and read the scroll area from
the frame in OnUpdate.
