"View source" but useful

[Aurel300]

(This may be an issue for api.haxe.org specifically.)

I would like the "View source" button for e.g. sys.io.File to be a dropdown menu showing these entries:

• the core API specification (https://github.com/HaxeFoundation/haxe/blob/development/std/sys/io/File.hx)
• the eval stubs (https://github.com/HaxeFoundation/haxe/blob/development/std/eval/_std/sys/io/File.hx)
• the eval source for StdFile (https://github.com/HaxeFoundation/haxe/blob/development/src/macro/eval/evalStdLib.ml#L980-L1051)
• similarly, the stubs or sources for other platforms

I realise the eval source linking is not trivial and would need some clever way to mark the position, ideally automatically generated from the latest evalStdLib file (search for module StdFile = ... end ?)

Apart from that, dox should have enough information about the types and the various platform-specific files it has to merge.
