Add string to mode_t parser added new function string_to_mode(char *m_string, mode_t base) which parses a given string and converts it to a mode_t. If either + or - are part of m_string the permissions are either added or removed from base. Currently support for permision copy is missing (e.g. g=u), but all other flags should work. Format for m_string: either symbolic modes or octal representation. symbolic modes: [auog][[+-=][rwxst]*] examples: string_to_mode("u=rwx,g=rw,o=r", 0); string_to_mode("a-x", 0777); string_to_mode("0744", 0);
