string_find renamed to string_pos + header update

- Renamed get_clamped to math_clamp for consistency (libs should use namespace prefixes)
- Nuked above/below macros and renamed unsigned_comp to insigned_int_compare, because it doesn't work with floats
- Replaced sprintf2 and string_pos with macros (due to new metarules)
- Add a few entries to functions.yml

   String parse functions. Idea taken from KLIMaka on TeamX forums.
   Placeholders in format %d% are replaced from string. d refers to variable index (starting from 1).
   You can repeat one placeholder multiple times, or use placeholders in any order.
