Merge Docker resolutions
This brings in some updates from a post on the ace-am dev list which mentioned that monitored files were not being marked as missing. This stemmed from using InnoDB in a docker container which has stricter rules are transactions compared to MyISAM.
In addition, I noticed that the css for servlets was not being loaded as the wrong mime type was being set upon transmission. This stemmed from adding utf-8 support in which we overrode the Content-Type response header.
