0.5: Custom gamma table

3.60-only

Notice: This plugin won't do anything out of the box, you need to customize the gamma table yourself and figure out what each number does.

This update allows users to customize the gamma lookup table that is used for brightness levels.
The table vitabright_lut.txt is the original one unaltered, it needs to be placed in ur0:/tai/ or ux0:/tai (ur0 has the priority).

Each line in this file corresponds to a brightness level, there must be exactly 17 lines plus an empty one a the end. Each number has to be a 2-digit hexadecimal integer (so from 00 to FF).
