[Feature request] Add «zeal_path» setting

[Kristinita]

Request

Add "zeal_path" setting in DashDoc.

Justification

I install Zeal Portable for Windows in E:\Zeal folder. But now if directory of Zeal not default I can not to use DashDoc.

Extended behavior

Setting "zeal_path" in DashDoc.sublime-settings file. I make a value "zeal_path": "E:\\Zeal" and DashDoc works for me.

Environment

Operating system and version:
Windows 10.0.14393
Sublime Text:
Build 3126

Thanks.

The windows version doesn't call the zeal binary directly, it uses start to open whatever handles the dash-plugin:// url scheme.

It might be possible to fix this, but I lack the expertise (and a windows system) to do that. PRs are welcome.

Fixed this by deleting registry entries for the dash-plugin protocol then rerunning zeal
