#102 File counts report lumps upper case extensions

[Bo Turnbow]

Files with upper case file extensions get lumped together in "Others" in the "File Types" table on the "File Sizes and File Counts" page. This problem was partially addressed in bug #1757394 (https://sourceforge.net/tracker/index.php?func=detail&aid=1757394&group_id=57558&atid=484569). A better fix would be to change the regex pattern to ".*[^.]\\.([a-zA-Z0-9_-]+)". That pattern is on line 19 in FileTypeReport.java.
