Add support for launching Eclipse Process in a system terminal session

[laeubi]

Currently processes are launched as a forked process without a terminal session attached to them. Some features of processes require a terminal session (e.g. autocompletion) and currently not work when running from within eclipse (e.g. the gogo-shell).

This is an attempt to bring terminal session support to Eclipse to support real terminal application similar to what is supported by IntelliJ.
