Implement !autobuild command

The `!autobuild` (or `!ab`) command allows you to build a record without needing to add every id. Missing trekkers/discs/potentials/melodies will be auto selected by the server.

Usage:
`!autobuild [character/disc/potential/melody ids...] lv[target record level] s[target record score]`

Examples:
`!autobuild s99999` = Creates a record with a random main trekker with the max score.
`!autobuild 103 lv30` = Creates a record with this trekker at record rank 30.
`!autobuild 155 132 107 s25000` = Creates a record with these trekkers with a record score of about 25000.
`!autobuild 103 510301 510302 510303 510304 lv20` = Creates a record with this trekker and these potentials at record rank 20.

Notes:
- Target level overrides target score. So a command of `!autobuild lv30 s1000` would have a record rank of 30 and NOT a score of 1000.
- If there is no target level or score, the command will default to a target level of 40.
- You can only add trekkers/discs that you own.
