Update Patches/Data Mod for 5.9 correctly

Requires:
Adding the original version of changed strings to the .ini files of a patch
Updating mods such as x3 that depend on current balance
Keeping the old mods based on 5.8.1 around for viewing recs (The mod list is becoming quite large... Might need to make this an on-demand thing)
Updating version numbers in the modlist txt file
