Feature suggestion: Add style preview or sample beside selection

[simongcc]

Thanks for creating such convenient tools. For instance, I am new to it and found that there are a lot of style preset. However, there are too many of them to try. So I suggest if possible add a preview / sample style beside each selection which could help quickly choose the right style.

Thanks for the suggestion! I'll add this to the list of improvements for Code Blocks, but I can't guarantee that I'll get to it anytime soon.

In the meantime, instructions for previewing themes can be found in the README: https://github.com/alexwforsythe/code-blocks#previewing-themes
