FIX: Fixing bad_alloc in setOutputBaseName().

• setOutputBaseName() checks for prefix of filename (stuff before dot). If no dot is present, the size of the char buffer depends on the address of the basename_source. This lead to sporadic bad_allocs.
• Now, we create the temporary basename in MPQCJob::Work() with a ".in" suffix.
• Moreover, setOutputBaseName() checks whether a dot is present and if not just takes the length of the given filename.
