Fix #41. Refactor addEvent.php
Remove unused point categories
Fix #30. Add the ability to mass input attendance via column based attendance
Add ability to choose which values indicate attendance

For events like community service the chairmen often record the number of hours per person rather than just a 1 for attended. The C now has the ability to choose how he would like the input to be processed. The process function will treat any positive number as attended if the checkbox is checked.
Add placeholder text to the textarea with instructions on how to mass add attendance
Uddate mass add attendance function to treat any number > 0 as attended
Merge pull request #45 from pitt-delta-chi/add-attendance-functionality
