Subject: Code restructuring

Time came to split ini_config.c
into many much smaller pieces.

1) ini_parse.c - will have parsing functions
2) ini_get_value.c - will have single value
interpretation functions
3) ini_get_array.c - will have array interpretation
functions.
4) ini_print.c - error printing
5) ini_defines.h - common constants
6) ini_parse.h header for parsing functions
7) ini_list.c - will have list processing functions
