Disable hiding symbols & inlines

* Having the '-fvisibility=hidden' and '-fvisibility-inlines-hidden' flags enabled gives clang warnings, regardless of the project's visibility settings. Figure there's really no reason to hide Boost's symbols anyways, since it's just being linked into a different project anyways.

+* Disabled hiding symbols & inlines
+  - This was causing clang to throw warnings, regardless of the project's
+    visibility settings. I don't see any reason it needs to be enabled
+	anyways.
+
+	If this causes a problem for your project let me know and I will add a
+	CLI flag to optionally add them back in (or just do it yourself &
+	submit a PR!)

 * Fixed universal build to allow for build directories that contain spaces
