Did you know you could type into a list to search it by prefix?!
The Lindens didn't!!
Let's make this search bar an ACTUAL FILTER!
To do this, we add support for filtering to all scroll lists,
so that's cool. Also filtered items will be selected.
Also optimized item selection loop to perform better when selecting in
massive lists (like group members)
Changed the text on the Copy Button to reflect that it copies everything,
not just the applied filter... if you wanted that, you could just
ctrl-a, ctrl-c... I mean, reallly
Params for LLScrollListCell, LLScrollListItem, and LLScrollListColumn
Moves code block for creating a LLScrollListCell out of LLScrollListCtrl::fromXML and into LLScrollListCell::create
Removes mDefaultListTextColor from LLScrollListCtrl, it is now used only in LLScrollListCell::create
Adds LLScrollListCtrl::addRow and LLScrollListCtrl::addColumn functions that take these Params
Separators are now built from an icon.. we may want to tweak it in the future, looks alright though
LLFloaterAvatarList::refreshAvatarList now builds elements with these Params instead of by LLSD
