Test log with highlighting

Options dialog

The note about "Follow tail" mode: it can be changed on per-tab basis. So you can enable "Follow tail" for one file, and disable it for another. This also can be said about the "Wrap" option.

The file highlighting feature currently supports 20 different colors. Lines can be matched using RegEx, so you can use one color option for seleral different words: you should specify "word1|word2|..." for this.
