Parent issue: #52

Add an optional 4th section to grammar files. The 4th section will be populated by Python semantics. When a grammar files is written with four section, its structure is as follows:

lexical specification
%
syntactic specification
%
syntactic checks/helpers written in Java
%
semantics written in Python
Existing 3-section grammars should function normally.

When a 4th section is detected (even when empty), it will generate the Java code needed to generate JSON ASTs. Note that the 3rd section could also be empty, and it would behave the same.

refactor: enable Python when grammar has 4 sections
c597eda 
This is in anticipation of a new hybrid Java/Python mode
in which the parser runs in Java and the semantics rep-loop
runs in Python.

In this commit, when an optional 4th section is detected,
plcc.py generates ParseJsonAst.json. Thus allowing the
parser to to generate JSON ASTs when the `--json_ast`
flag is passed. It also generates experimental Python files.

Closes #95
