Add ALEInfo command to get list of available/enabled linters (#273)

* Add ALEInfo command to get list of available/enabled linters for current filetype * Add Vader tests for ALEInfo command * Fix ALEInfo tests breaking CI by echoing too much output to screen * Speculative change to Makefile which seems to fix test hanging problem locally. * Fix Vader tests to not require a TTY
