#942 Intel toolchain as of 28apr2014

My first pull request so please bear with me as I try to figure out how to do this properly.
@JackPerdue: I don't see the need to include these comments in the easyconfig file (since it's not included in the other `ictce` easyconfig files either).

Also, there will be a pull request for an `intel` toolchain soon, that will have a version like `2014b` (to indicate 2nd half of 2014). The idea is that this can be a common toolchain to be used by the EasyBuild community (for whoever sees the need to, no pressure). The framework support for this is contributed in https://github.com/hpcugent/easybuild-framework/pull/956. More on this later on a mailing list near you.

One key difference between `ictce` and `intel` (next to the name and the versioning scheme) is that we will include `GCC` as a dependency for the Intel compilers there, rather than depend on the system GCC like is done in `ictce.
