Skip some of the 'garbage' in the string that we don't want to use to sort on.
This way the alphabetical sorting will work better as we would be actually using those characters instead of some other characters such as spaces and tildes at the begin of the name.

bool strtolower | ( | char * | str | ) |
Convert a given ASCII string to lowercase.
NOTE: only support ASCII characters, no UTF8 fancy. As currently the function is only used to lowercase data-filenames if they are not found, this is sufficient. If more, or general functionality is needed, look to r7271 where it was removed because it was broken when using certain locales: eg in Turkish the uppercase 'I' was converted to '?', so just revert to the old functionality
