currently: if a == 1: # run sequence elif a == 2: # fight sequence

fix: if aout == 1: # run sequence elif aout == 2: # fight sequence

Made it so you can select amount of days, use "a"/"all", "h"/"half", and percent values in sell and buy menus, fixed a bug

During the banking and especially the loan shark sequence after jetting to Bronx, typing in the exact number to repay your debt is a little tedious. It's not that big of a deal, but I think it would be cool to be able to type in 'a', 'all', 'half', or a percent value to select exactly how much you want. This could also be applied to buying drugs in amounts depending on how many you can potentially buy.

Loving the game btw
