Commit 99454be3 authored by Evan Prodromou's avatar Evan Prodromou

Move activity classes to their own files

Moved the various classes used by the Activity class to their own
files. There were >10 classes in the same file, with around 1500 lines
in the file. Just too big.

This change makes autoloading work for these classes, so also removed
the hard require in lib/common.php.
