Comments styling issues

[stefanosgeo]

The submit button in the comments goes out of the modal body

Also the resolve checkbox in an existing comment is, IMO, too big in compare with the "resolve" text on the right

I am not sure if this is the same css rule/class, but the same happens if you try to change the location to a scheduled event in the scheduling tab.

I created a PR for the view in your first screenshot: #565
And I am seeing now, that the CSS I removed in my PR messed up the view in your 2nd screenshot :P I will add more commits to #565 so it fixes the 2 first views you posted.

Fix for the scheduling tab is out: #572
