Mads Hartmann 8ca2ecd52d Add support for exporting environment variables (#4) 
* Add support for exporting environment variables

* Support multiple exports in one command

Also improves the structure of the AST so the variable name and the
assigned expression aren't free-floating

* Allow for multiple declarations in local declarations as well

Simplify the generated nodes.

* Commit generated code

* Consolidate declarations into a single declaration_command

This also adds support for declare, typeset, and readonly

* Rename environment_variable_assignment to variable_assignment
