* Colorize comments that hint type of data
* Use new colors for comments that hint type of data
* Colorize local variables and args in disasm
* Fixed leak in r_anal_var_all_list()
* Refactoring + rename color func_arg* to func_var*
* Updated all color themes for func_var* colors
* Directly query sdb for faster and cleaner var colorizing in r_colorize_opcode
* Remove hackish r_core.h include in print.c and use callbacks instead
