bash scripts to aid linux deployments
Changes to get the bot to work without the dependicies bundled in Debian.

The install script contains exceptions for the two dependencies which are not packaged, these are:
* pircbotx
* sqlite-jdbc

We'll need to do something about that if we want it packaged and running properly (probably package them myself).

Still TODO on this branch (before merging hopefully):
- check pidfile (I think this is wrong at the moment)
- check where the database is going (and where it should go)
- Write systemd service
- Write initscript (for things not using systemd yet)

Out of scope stuff
- Putting the stuff from unix-install into a package
- Fixing the dependency oddness in unix-install
bot pid, user and workingdir fixes
