Support intellij import

[OlegYch]

Unfortunately it looks like fix for #3 broke import in intellij.
With 0.5.0 imported project looks like this:

With 0.5.1 idea complains about

3:00 PM	Duplicate content roots detected
								Path [D:/Distrib/Coding/Java/scala/scastie/api] of module [apiJVM2_11] was removed from modules [apiJS2_13, apiJVM2_10, apiJVM2_12, apiJVM2_13]
								Also 1 more path was deduplicated. See idea log for details

and result looks like this:

and cross-built module sources are not available in other modules

👍 I'm trying to work on Zinc 1.4.x but running into this problem. Maybe for IntellIJ it would be better to just focus on a single instance?

@eed3si9n How could I configure sbt-project-matrix to add SettingKey("ideSkipProject") := true to all but the first project stamped off the template project?

As a workaround maybe I could make some directories under a dot directory like .sbt/matrix/fooJVM2_13 and use that as the base directory? That way the build users can ignore them.

I'm not sure if there's an easy way to say all-but-the-first-row, but I guess you could say

SettingKey("ideSkipProject") := scalaVersion.value.startsWith("2.12.")

that sounds good

@eed3si9n thanks, it works
(though deleting .idea and reimporting the project seems necessary)
