Improve theming / customization controls #4
Description
The way that IDA applies themeing makes it hard (maybe impossible) to change the colors of the 'call hint' dialog that the iPython console pops up through simple CSS. I actually had to tweak the plugin code.
As such, I was thinking it might be better to just make some simple theme/palette file kind of like lighthouse. It also gives us an opportunity to ship better default (bright) and dark themes for the console.
