- Bumped the major version, non new features expected since this year class is done.
- Added the parameter fail_on_error to the liblet.antlr.ANTLR.context method to make
it return None in case of parsing errors

parse errors
- The liblet.antlr.ANTLR.tree method does not include nodes for the EOF token.
