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.

The above mentioned settings are per account.

Fix Issue 1012: Private voice call

The original purpose of the patch removed here was to fix this very bug, though I could not reproduce it at that time...
There must still be an edge case where this bug will reproduce but I tweaked the involved settings around quite a bit and could not reproduce it
Added a third option to hear voice from everywhere so position does not affect volume/panning.
