Delete or update the kaitai_struct_visualizer_java.iml file

[generalmimon]

When I see the following:

kaitai_struct_gui/kaitai_struct_visualizer_java.iml

Lines 15 to 16 in ae342c4

	<orderEntry type="library" name="Maven: io.kaitai:kaitai-struct-runtime:0.5-SNAPSHOT" level="project" />
	<orderEntry type="library" name="Maven: io.kaitai:kaitai-struct-compiler_2.11:0.5-SNAPSHOT" level="project" />

it is a clear sign that something needs to be done with this file. IIRC, nowadays it is automatically regenerated by IntelliJ IDEA anyway, so it would be best to remove it and Git should ignore all *.iml files.

Yep, the .idea directory and *.iml files should be deleted and put into .gitignore. We already have a Maven build, and as you say, IntelliJ uses that to automatically generate its own project files.

In my experience, having an existing IntelliJ project in the repo is actually less convenient, because then when you import the Maven build, the generated project files collide with the ones from the repo. At best you only get some unnecessary Git changes, at worst the resulting project behaves unexpectedly/wrong.
