Bug fixes

- Made char limit of session titles
- Removed the right alignment of chat authors to prevent cut off of usernames in cat
- Changed horizontal alignment of chat to increase room
- Made it so we only use the lower case version of the argument when referring to event by shortnames in the url or when updating/creating events.

NOTE:
we should migrate to the new shortName version by make all the current shortNames of the events to be the lowercase version.
