* cleanup GetTrackName()
* a few more changes to change mod_zone_bonus & add Track_Bonus_Last
* fix undefined symbol sTrack
* fixup !bwr for multiple bonuses
* fix GetTrackName() after I broke it
* add bonus number param to help text of sm_bwr
* fix !wr after I broke it adding !bwr [bonus number]
* ignore checkpoint zones for now because nothing is ready for them
* update points for bonus #2 through #8 at same time
so instead of something like `9 (track count) * 22 (style count)` queries, it'll do `3 (main, bonus1, rest of bonuses) * 22 (style count)` queries and the rest of the bonuses on the recalc all in the same query
Now I can push database migrations without making the plugin's users do the querying on their own.
List of migrations:
* **Converted all SteamIDs in the database from SteamID3 to Steam Account ID format. The difference is simply stripping of the [U:1: prefix and ] suffix. This change speeds up the queries and reduces the database's size by a lot.**
* Removal of `workshop/` paths from all map names in the database.
* Added index to `lastlogin` to speedup the filtering I added to rankings with `shavit_rankings_llrecalc`.
* Removed `country` from database. It was completely unnecessary.
* Converted IP addresses from plaintext to a single 4 bytes integer.
* Converted `date` of records from a string to integer.
