There are two types of font names, the camelcase and the all uppercase
Since mostly uppercase is used for scroll lists, this issue went undetected
but both types are used upstream, so we now look for camelcase if we couldn't get an uppercase one
The crash itself is avoided by falling back on SansSerifSmall if no known font has the name provided.
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
