Previously, ProgrammingGroups could have been undefined in rare cases. Therefore, we check whether the variable is properly defined before calling the method.
Fixes CODEOCEAN-FRONTEND-7D
Further, we remove the "check invitation" button and extract some methods to our new ProgrammingGroups object in JavaScript.

This change allows us to use the session ID immediately for the connection_change and connection_status methods. Hence, we can identify different browser sessions of the same user.
Previously, we were at an ACE editor published between 1.1.8 and 1.1.9. This caused multiple issues and was especially a problem for the upcoming pair programming feature. Further, updating ace is a long-time priority, see https://github.com/openHPI/codeocean/issues/250.
Now, we are not yet updating to the latest version, but rather to the next minor version. This already contains breaking changes, and we are currently interested to keep the number of changes as low as possible. Further updating ACE might be still a future task.
The new ACE version 1.2.0 is taken from this tag: https://github.com/ajaxorg/ace-builds/releases/tag/v1.2.0.
We are using the src build (not minified, not in the noconflict version), since the same was used before as well.
Further, we need to change our migration for storing editor events. Since the table is not yet used (in production), we also update the enum.
* This commit refactors the table used to store events.
* We also use a UUID as session identifier in the synchronized editor to support multiple concurrent tabs opened by the same user.
* Further, we renamed some methods to make them easier to distinguish.
This commit mainly changes the color definitions. Mostly, those changes are semantically equally, but there are a few changes that occurred to align the color scheme within the app.
