Add `--version` CLI option #59

Closed vvv closed 5 years ago

vvv commented 5 years ago

When reporting bugs or comparing --help outputs of different hasktags executables, one may want to know which version of ‘hasktags’ package was given executable compiled from.

This information is best served by dedicated --version option.

$ hasktags --version
hasktags-0.70.1
