[Extra Metadata Loader] Allow custom width/height sizes

[MrWheyne]

Extension name

Extra Metadata Loader

Feature Description

Currently the logo loader settings only allow for logo sizes down to 300 pixels minimum (width), which is somewhat limiting if I want my logos smaller. Adjusting the height both solves and creates a problem, because while horizontal logos become OK, vertical and sqare logos become too small. My suggestion is simply to make the sliders go from 50x50 (minimum) to 1000x1000 (maximum), and use increments of 10s instead of 5s (since I don't know who would use 5s anyways).

Screenshots

Current limit makes Jak II logo too big. Idea is for all logos to be the same size as the Play button.
