An empty file should be expectable

[sparsick]

A file without content should be expectable. Currently, FIT doesn't accept empty <tr></tr> . It throws following exception:

    java.text.ParseException: Can't find tag: td
    at fit.Parse.findMatchingEndTag(Parse.java:86)

With an empty <td></td> the exception isn't thrown, but a comparison isn't done.
