Added parent POM `plugin-profiles` for common plug-in settings

[dotta]

For building the plug-in you now need to pass 3 profiles:

• eclipse-indigo or eclipse-juno: To decide whether the build is targeting Eclipse Indigo or Eclipse Juno.
• scala-2.10.x: To set the Scala version. The only currently supported profile is the one for Scala 2.10.
• scala-ide-stable, scala-ide-dev or scala-ide-nightly: For the Scala IDE version that will be used as a targeted installation for the build.

The ./build.sh script is now the simplest way to build the scala-search plug-in. The default build targets Eclipse Indigo and the latest Scala IDE stable release for Scala 2.10.

@mads379 The kitty will fail to build this because I need to update the Jobs to pass the correct profiles. If you are fine with the changes I'll do so, ask the kitty to build again and merge. Let me know.

@dotta Looks very good! Nice to be able to remove all that xml :) :+1:

I tried the code locally and it works just fine. I'm going to assume that kitty is making a fuss over nothing and merge this.
