Fix crash when attempting to translate a NULL string
Always allow pubkey file to be loaded.
Minor bug in Sys_LoadDll. The first check for libhandle will return and unless you're running developer 1 you'll never see the error message which caused the game not to load.
Remove status reporting from Sys_TryLibraryLoad.

Without this, the preceding commit will cause double reporting of errors if
developer=1.
