Add new aa-comma-style all-except-single-line. (#80)

* Add new aa-comma-style all-except-single-line. This option will enforce "always" for multiple line AA but for single line AA it will enforce "no-dangling".

* Switch from adding new style to fixing "always" to not require an optional comma for a single-line AA.

* Fix condition check and linter issues

* Switch to function for late evaluation

* Update the expected aa-style-always.brs results.
