Add function add_gear_to_UI to gui.py

Added the function add_gear_to_UI to the gui.py module. This function is
used to load the items file that the user selects and adds the gear
names to the corresponding item name boxes and in the future this will
also add gear into the dps calculations.
Add functions to handle item mods to itemstats.py

Added functions to parse the item properties, explicit mods and implicit
mods to itemstats.py. These functions add the corresponding values to
the item info dictionary. The itemstats.py module returns a dictionary
with socketed skillgems per item per socket group, and all the mods of
an item.
