More cheat clean ups and added some more cheats
Added button info to the code format at the top of the file for the R4 type
Added placeholders for the games in the softwarelist with no cheats so that there is somewhere to insert the cheats quickly
Added basic header to top of cheat file. Started work on further cleaning up the cheats to work better with Duckstation - grouping, re-sorting, fixing typos and format discrepancies, adding some cheats and removing a few duplicate cheats.
Converted MAME format cheats into DS format, fixed issue with some games having multiple headings and made the headers more verbose with square brackets to help them stand out.
