One bug fix and two feature additions

Hi! I've made three changes that I think would be useful to others. Obviously the bug fix would be useful (though it isn't obvious in your current version, it appeared when I added an additional column to the table). The logic to parse include files is a necessity for us, and would likely be useful for larger sites. Adding the last access time to the overview page was a must for our use case, and it seems like something that may be of interest to others.

Take a look and let me know if you need any changes to the code for it to be acceptable.
