Support includes when opening SFZ

[audio2000]

Some people that create SFZ instruments use "Includes" within their main .sfz files to link to other .sfz files (usually found in a folder called "modules"), which usually contain the paths/links of the actual samples that that sfz instrument uses.
If you try opening one of these SFZ instruments using Polyphone, they open but do not show any samples in the Samples category.
Suggesting that maybe support can be added to allow Polyphone to recognize these "Includes" used in some SFZ instruments, when opening.

I tried looking around to find you a couple of examples of SFZ instruments that contain the "includes" that I am talking about, here are a couple, hope this helps.
