IDE support for frege

Motivation

1. one impl for eclipse and intellij IDE support
2. decouple frege lang/compiler evolution from IDE support
3. secondary: haskell IDE support

Implications

1. abstraction for eclipse and intellij will introduce fuzziness
2. some type introspection will be only available on compile time
3. compilation requires feed-back channel for in-IDE display

Current state

1. idea is born
2. maven setup for eclipse
3. PoC of some language features' interpretation
