Starting work!

Dat goto tho
Mission listing

Including the necessary SQL to determine how much commodity cargo is
worth at its destination
Tweaking SQL for getMissionList

Simplified to use aliases for price at the cost of non-commodity cargo.
More mission viewing abilities

Along with a handful of tweaks to the CSS and event logging that
technically shouldn’t be in this branch but whatevs
Can't stop tweaking

Also a reminder that YOU’RE ON THE WRONG BRANCH
Do you like SORTING THINGS?!

Because now you can SORT all SORTS of THINGS. Just so long as those
THINGS are valid <tables> with <thead> and <tbody>. Don’t forget that
<table> needs a SORT class applied.
Generic "I don't want to lose my work" commit
Cargo SQL overhaul

The SQL for retrieving a pilot’s cargo stats (tons occupied, available
and the cargo meter) has been rewritten to include mission cargo and
overall work better.
Quick fix to cargo SQL

Ran into parameter availability issues on $pilot->getUserPilot().
Should be corrected now.
Also updated $pilot->getPilotCargoStats to allow manual specification
of a pilot ID. Futureproofiing!
Mission deliveries

Deliveries now work and payout properly.

Caught a nasty bug with the cargo SQL where it was returning NULL
values if it couldn’t find any cargo. Now returns 0s
