Significant rework to abstract common functionality using Willie config files

* Can now prefix every command by a single character to support v prefix on vert
* Resolved "setup" function not being able to schedule tasks with a patch to willie
* Abstracted api url and site name
* added commas to some number outputs and used format rounding functionality
Removed all globals usage and fixed several mistakes with float formatting. Added a last_block command to test the output for new blocks easily
Move to generic module name
Bugfix for sending messages from non WillieWrapper bot object
