Laravel theme #23

Hey, thanks for those awesome themes. My personal favourite is Laravel (despite never having coded in PHP, lol) but I found some issues with it.

1. I really enjoy the fact that variables are white (DEDEDE). I really helps to distinguish them from method calls. In the original Laravel theme from rainglow.io function arguments are also DEDEDE but in this plugin function arguments are FC580C:

2. Class names are FFC48C instead of DEDEDE:

3. Unknown symbols (such as method names with a typo) are missing Underwave which makes them undistinguishable from properly named methods.
   It can be changed under Errors and Warnings -> Unknown symbol

4. Outlined entity has a foreground nearly the same as Editor background.
   It can be changed under Code -> Outlined entity. I guess it can be completely removed or changed to Bordered effect
