FMSLogo Code

Remove "Port FMSLogo to a supported UI tooolkit", since this is complete as of FMSLogo 7.0.0.
There is still more work to do to make it a pure wxWidgets application, but the OWL version has been deleted, which was the last step mentioned in this task.

Update the release cycle to match the current practice.

Update the icon to match what it looks like in FMSLogo 7.0.0.

Remove the request for a new icon, since FMSLogo 7.0.0 has one (provided by Jan-Niklas Grabe).

Change the old SourceForge 6-digit ticket numbers to the new ones
that are 1-3 digits. After a SourceForge site upgrade, the ticket
numbers were re-created to be per-project and the old numbers are
no longer visible. As a result, the old numbers are completely
useless as a ticket reference.

Ignore the Polish manual.

Tag the code used to build FMSLogo 7.0.0.

Prepare the files for the release of 7.0.0.

Mark the files as having native line endings to make them easier to modify on Windows.

Update the translation tables in preparation for the 7.0.0 release.
