Reuse the Java icons for PHP filetypes

[rafaucau]

It would be nice if there were different icons for PHP filetypes such as class, interface, abstract class, attribute class, trait, enum, etc.

You may want to use a IconPathPatcher. Instead of replacing icons of files by file name with an IconProvider, an IconPathPatcher replaces icons by their name. Per example, it can replace Interface.svg by your own icon. You can find icon names (actually, their path, like /expui/nodes/Interface.svg) by entering in Internal mode.

In other words, you may want to mix IconProvider and IconPathPatcher. Please note that IconPathPatcher is applied once on IDE startup, while IconProvider is applied each time an icon is displayed.
