FGU Dark Theme, Selected Filter text Unreadable

[Griogre]

In the FG Dark Theme the filter highlighted selected text is white letters in a light blue background which is very hard to read.

To reproduce, selected the Dark Theme, load the DMG, click the Tables sideboard button, and type in 100 and hit enter. Note this is true for *any* selected filter text not just the table one.

Related: The current hp text in the Combat Tracker is also very hard to read with this theme, as it is a dark shade of green.
