Resizable text fields; Font size preferences; Customizable snippet tags; List headers annotated with number of occurrences.

Hi,

I've made a couple of improvements for personal use, which I do think are useful in general.

* Text fields will now resize properly when the window size changes.
* The headers in the list view now have the amount of found comments next to them in brackets to provide for improved overview – e.g. like "TODO (4)"
* The font sizes used in the list view are now switchable between "large" and "small" via a preferences panel.
* The actual snippet keywords that are scanned for are now customizable via a preferences panel, e.g. new ones can be added or existing ones deleted/edited, and they can be reordered. This is useful if you want to use additional keywords, such as TESTME or REMOVEME. The original "FIXME", "TODO", "???" and "!!!" remain the default settings.

Thanks for your consideration,
Georg
