[JBIDE-13616] removed typed application classes and interfaces

There were still typed application classes and interfaces ported
from the legacy client library:

- IPHPApplication
- IPythonApplication
- IPerlApplication
- IRawApplication
etc

- JenkinsApplication
- JBossASApplication
- RubyApplication
etc.

They're not used and were a bad design decision anyhow. We now got
rid of them
