[semester-upkeep] Enable semi-intelligent compile diff and single-command execution

[jmuchovej]

Just a note, when referring to groups... groups := {intelligence, core, data-science, supplementary}

Feature Request, for autobot

Description Currently, autobot naïvely recompiles every aspect of a meeting, this isn't necessarily the most expensive operation – but it's generally unnecessary; if we can recompile somewhat intelligently, that would be ideal.

Also, if we could run specific commands from autobot, rather than having to either comment out the source or do some importing voodoo (into a REPL), that would be ideal, too.

Needs

• Enable semi-intelligent deduction (of the meeting to re-compile)
• Allow for the specification of single commands (auto-generated from the different functions that are run in semester_upkeep(...)).
