More flexible file selection in Squirt

Just a quick post to note that the file selection in Squirt is now a little more flexible and will now find a selected pattern anywhere in the file name rather than just at the front. This change also offers the (unexplored but potential) advantage of allowing for the use of regular expressions when selecting files.

In other news, the ls action now returns the file information (file size, date changed, etc.) rather than a simple list of file names.
