Add -relative option to ALESymbolSearch

[chaucerbao]

I added the -relative option to ALESymbolSearch, and the associated test.

However, I only use TSServer, which doesn't seem to be implemented for ALESymbolSearch, so I'm unable to actually test the -relative option IRL. I kept changes minimal, and the existing tests pass. But I would certainly prefer a quick real-world test to confirm.

Thanks for working on this too. 👍 I wouldn't worry about tsserver just yet. I might have a go at implementing symbol search for tsserver later. See my comments here.

I think this is generally good, so you can update the documentation for the command to mention the new switch.

@w0rp What's the best way to request another review after change requests are addressed?

Check out 19cc724 and examples in test/test_parse_command_args.vader. I have now added a function for parsing command arguments we can use everywhere.

If you wait, I'll look at the pull request eventually.

Gotcha, didn't mean to nag. It just isn't clear what state the PR is in after a change request since it stays as "Changes Requested". More of a GitHub issue, I suppose.

Perfect! 👌
