syntax/ebuild.syntax: new syntax file based on sh.syntax

Fixes:
 * Added proper highlighting for externally visible global .eclass variables
   (S, SLOT, SRC_URI nad problems before)
 * Added new .eclass vars and functions
 * Added more colorful " " highlighting
 * Added more shell keywords like 'if', 'then', 'else', 'export', 'unset' etc.
