Modernization of LLFloaterBump that took place while working on the issue solved in next commit
Fix the crash upon opening Bumps, Pushes & Hits Floater

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.
