build with gradle-intellij-plugin

I've updated how to use this new setup for importing into IntelliJ. Due
to an issue with how intellij does import you unfortunately have to
revert the imports changes to .idea after import to get the
preconfigured runconfiguration. There's also a couple ugly hacks to support
multi-plugin projects which will be fixed when
 JetBrains/intellij-platform-gradle-plugin#17 is fixed
in a few days.

-Gradle builds fail on Windows due to reliance on the fetchIdea.sh shell script.
-This script simply downloads and installs IntelliJ IDEA code for building against
-and shouldn't be too hard to port to Windows. See 
-[Issue 167](https://github.com/GoogleCloudPlatform/gcloud-intellij/issues/167).
-As a quick workaround you can manually download and install the relevant 
-IDEA distribution and comment out the loadIdea task in 
-[build.gradle](https://github.com/GoogleCloudPlatform/gcloud-intellij/blob/master/build.gradle).
-
-On Windows you should be able to build the plugins inside IntelliJ by
-selecting "Prepare All Plugin Modules For Deployment" from the Build menu.
+* $ ./gradlew runIdea: run IntelliJ preconfigured with the plugins from this project.
 
 ## Configuring and Debugging in IntelliJ
 
 ### Import Project 
 
-To work in IDEA, just "Open" the cloud-tools-for-intellij directory 
-(the root directory cloned from Github) from the IDEA opening screen.
-
-Alternately you can select "Import  Project" from the IDEA opening screen and 
-choose the root build.gradle file. In this case, IDE features for IDEA plugin
-development may not work; and run and debug configurations will not
-be available from within the IDE. However, you can run and debug unit tests.
-
-### Optional:  Downloading source for IDEA to debug.
-
-[Download the IDEA source tarball from JetBrains](http://www.jetbrains.org/display/IJOS/Download) 
-into your home (or any other convenient) directory. Extract it and 
-add the resulting directory (usually something like ideaIC-141.1532.4) 
-in the Sourcepath tab of Project Structure > SDKs for the IntelliJ CE 141.1532 SDK.
