[Rando] Add Check Type Filters to Check Tracker

[Caladius]

This enables granular filtering of Checks, both by means of text search as we previously had and now with buttons that enable filtering only the selected check Types. Also added a checkbox to the settings to toggle showing Filter Options at all.

Clicking on an icon will show only that types Checks in the list, clicking the red X at the beginning will clear your selected filter types.

I really like this. I have two recommendations:
-Add hover tooltips for the filter icons. I have a hard time telling which filter is which.
-You do (RCTYPE_MAX - 1) / 2 to achieve a 10 column layout. You could add instead of subtracting the 1 and then this would get you 2 rows instead of 3 which I feel is more visually appealing. This is purely a opinion, entirely up to you.

From my own testing, works with no fuss. I second the feedback above, especially for tooltips.
