Provide improved support for long property values

[merks]

• Make the MavenPropertyDialog resizeable and provide dialog settings to remember the size.
• Use a table layout for the property table of the MavenLaunchMainTab.

I literally needed to edit a value in some other editor and paste it because it just wasn't possible with the tiny limited-sized dialog:

The table layout also improves the use of the existing real estate.

A more realistic value that I was editing is like this one:

${file_extract_matching_pattern:${platform-dependencies}/pom.xml,UTF-8,<version.maven.tycho>([^<]+)</version.maven.tycho>,$1,3.0.1}

I'm experimenting with a dynamic variable where I can specify a file to be read with the given encoding, a pattern that's used to find a match in the content, a replacement string used to extract the content, and a default value if the pattern doesn't match. It's quite a bit to specify!

Looks good to me

Thank you for this one as well.

If one want's to enhance M2E's launch dialog further I think it would be good if one could edit property keys and values directly in the table without the need of a separate dialog at all.

Yes, as well up and down buttons. I know order doesn't matter, but it's still nice to organize.
