Add MySQL-python to production requirements

Added MySQL backend to the requirements.
Change project configuration
Changed __init__.py to take local_settings.py from local_settings.cfg.
This is a bit clearer to understand because the method to load the
settings is called from_pyfile(). Which loads a py file and could load
the cfg as well.

Added example_local_settings.py file to the project to allow another
user to have a blueprint for local_settings (bare minimum)
Fix index template

Added a newline between <p> tags in the index template. Just for
consistency.
Add Slet, Ticket and Rule models with DDL/DML statements

Added Slet, Ticket and Rule models to the project. These should
accomodate the basic needs we have for now. Such as having a collection
of Slets of which one is marked as current. We will be able to record
Ticket purchases and a simple Rule table for the Slet

Addded initial DDL/DDM statements. Which are in truth plain SQL
statement. No migrations mechanism yet :(
Add forms module

Forms module will house all the forms. For now it contains just a
placeholder.
Ignore solnyshko/local_settings.py

Updated .gitignore to ignore local_settings.py in solnyshko app dir
