Replace textual enum desc with an lov

The enum description in the calibration column of the parameters
table is often very long. It makes it very hard for the user to
see all the possible values an enum can take.

This commit replaces that description with a link. Upon clicking
the link, a screen pops up with a table with all possible values
the enum can take. The actual value is pre-selected.
Add more visual aids to find bar

two more nice-to-haves:
 - A search result counter (e.g. 3 of 5)
 - highlight search field red when there's no match
Restore original size and scroll preferences

During the previous commits, some of the previously fixed
defaults were erroneously deleted. This commit restores them
and also walks around some annoying behaviour when a JTable's
autoResize is OFF, but the JTable is smaller than the available
width.
Embed Filechooser directly inside Open File Dialog

No need for a pop-up within a pop-up.
Support opening files from command line

The implementation also provides support for limiting
the maximum number of read packets by using the -l
option.

The next step is obviously to implement some ranging
capabilities (e.g. 1000:2000). To be continued.
