Applying conditions

- Modifying the condition CSS classes in _table.scss to apply `!important` to definitely override the color value, without it the specificity of this class was lower than what was applied and thus had no effect
- `_handleConditions()`, `_saveConditions()`, `_checkSigns()`, and `_checkConditions()` functions all added to implement the logic for applying conditions saved in settings
- Updated `_formatColumns()` function to format all columns with its real id value from the table data so it can be referenced as is throughout the rest of the module code
- Additional constants added for condition values
Merge pull request #46 from stulees/chore/conditions
