Symbolic links

[sfornengo]

Describe the request

I am using arduino-ide and I would like to share header files .h between multiples projects.
The simplest solution is to use symbolic links, so the arduino-ide should be able to open .h symbolic links too.

Describe the current behavior

Currently when I put a .h symbolic links in my sketch folder and open .ino file it does not show symbolic linked .h in the editor.
