Added features to color scheme

[gcollic]

Hello, I added some features. Thank you for sharing your color scheme ;-)

• Added Regular expressions coloring (for languages such as Ruby)
• Changed invalid and separator colors (to be more like Visual Studio)
• Added links coloring (for languages such as markdown)
• Added color to escaped characters
• Added colors to "find in files"
