0.51 update

New Features

• Song search has been written internally and a rudimentary front end is accessible from the theme's "search" tab. Currently the search functionality only supports english alphabet character searches of song titles. Since the search filter is built internally the game will dynamically update your music wheel to only display the search results. Currently it also inherits the sorting method you have selected (only before you begin the search, changing the sorting method afterwards won't do anything) so if you have group sort enabled (the default) and you search for "kirby" the search results will remain filtered by their respective packs, if you select preferred sort which has no grouping to begin with then all of your search results will be displayed at once, and their pack can be determined by the indicator in the top right. The search will display the last valid set of results if you extend your search query such that no results are produced. Search by music artist and stepfile author (insofar as this is discernible) will soon be added, assuming the whole system isn't bad and buggy and I disabled it again.
• Added basic wife based grades: 99.98% = AAAA, 99.75% = AAA, 93% = AA, 80% = A, 70% = B, 60% = C. These are mostly for aesthetic purposes. They were determined from testing of initial values that droppedbass provided (thanks).

Fixes/Updates

• The maxhighscorelist preferences are now properly disregarded.
• The gameplay current percent score that displays above the judgecounter no longer gets colored by the latter's bg.
• Removed the 90% score requirement for receiving an SSR rating. You'll still get 0 if you get a failing grade. The restriction was initially imposed in order to prevent things like mashing a B on a 40 and getting an SSR of 30 and the like, further updates to the calculator will safeguard against this in a non-breakpoint fashion and since everything will be recalculated when the full implementation of the system is done anyway, I suppose it doesn't really matter.
• Lanecover movement speed cut to 10% of what it was in order to make it easier to adjust (its tied to the update function which is tied to framerate so it's still kind of a pain but this is a quick fix).
• Dark option row has been returned to the playeroptions menu.
• The player score calculator is more precise/immune to autoplay now (requires a game restart though). Calculation speed should be roughly similar, or perhaps even slower, but it'll get faster when I figure out how I want to implement the full recalculation system.
