Move showbot.rb to commands.rb

Moved Showbot plugin to Commands to better reflect what it does. Also to
make the project more general-use.
Alphabetize + Add new cinchize settings + new shared settings.

Alphabetized the plugin list and also added plugin options, also added a
new 'shared' section for cross-plugin options.
Remove freenode references

Removed freenode-specific references, replaced with 'network'. Left
freenode/#cinch-bots as the 'example' however.
Refactor existing options into chinchize.yml config options.

Refactored the options for admin.rb, schedule.rb, shoutcast.rb and
twitter.rb. Also some additions to cinchize.yml
Untested backup.rb changes.

I don't have the ability to test these changes, so i'll leave it up to
@mutewinter to test them and modify them if needed, but they should work
in theory.

Also updated the ReadMe to add new .env variables
More options + Moved the shared block to the right place, oops

Had the shared config options in the wrong place, also added more
options
So long Showbot!

More genericizing, pushed the last group of Showbot references to the
config
Update to use .ruby_version

This should be seamless, i hope.
Whoops, some whitespace issues.

Fixes cinchize.yml so it actually works again. :P
Missed changing this.

Correct the commands.rb class name.
Whoops, missed this one.

Noticed this one quick quickly in live usage, oops!
Removed the need for random.rb

Any modern version of ruby has the sample method for arrays, unless
there's another reason i'm not seeing for random.rb, might as well use
built-in functionality.
Readme.md update

Forgot to update the readme as part of the last commit.
Add i18n into the bot.

This is very minimal. This can be applied in a much wider case, but
solves the only required issue for now. Will add i18n support to the web
side of things in a future commit.
i18n-ify the web side of things.

This is a huge commit. I've i18n'd the entirety of the views.
There are a few small quirks. Feel free to improve. :)
Add an alias for I18n.t to t.

Makes things a lot neater.
Update this to use t instead of I18n.t

Leftover from before i added the alias.
Get rid of hardcoded development port; Readme.md update

Development port has now been moved to .env, updated the readme as well
to cooberate the change.
Add SHOWBOT_DATABASE_URL to .env

Added SHOWBOT_DATABASE_URL to .env. Changed the gemfile and instructions
accordingly.

This allows rake db:migrate to work with SHOWBOT_DATABASE_URL being set
in .env.
Update the gemfile.

TZInfo-data is now needed
