In source code panels, display known wxWidgets controls as a hyperlink

[KeyWorksRW]

Description:

It should be possible for source code views to use hyperlinks for known wxWidgets controls. This would generate a wxEVT_STC_HOTSPOT_CLICK event. On Windows, this would switch to the Docs panel and display a URL for that control in the current Panel's language. For Unix, until webview is working, this would mean passing the URL to the default browser.

With the new captch requirements for wxWidgets C++ documentation, we can't display the documentation in the docs window. Unless the captcha requirement is removed, or we decide to ship/install the webview2 distribution files, this isn't going to work for C++. It could, however, work for wxPython and wxRuby.
