Tool for porting IntelliJ themes to darklaf themes

[weisJ]

We should create a tool which automates porting IntelliJ themes to darklaf themes.

What needs to be done:

• Create the corresponding Theme class and appropriate directory structure.
• Parse the general theme properties
• Parse the icon properties
• Create list of properties, which may need to be individually overwritten by the theme. For an exhaustive solution this would be associating every color/padding property with the corresponding IntelliJ property. Then check if it differed from the darklaf default value and add to the overwrite set if necessary.
• Create the derived selection color properties
• Recommend properties for the derived accent color.
