Unicode lib native scripting

Command line variables might need to be renamed, otherwise this looks okay for native scripting.

Here is a test script using the names currently chosen:

#!/usr/local/bin/fontforge
Print( " starting name" )
temp = UnicodeNameFromLib(65)
Print( temp )
temp = UnicodeNameFromLib(69)
Print( temp )
temp = UnicodeNameFromLib(200)
Print( temp )
Print( " done name" )
Print( " starting annotation" )
temp = UnicodeAnnotationFromLib(65)
Print( temp )
temp = UnicodeAnnotationFromLib(66)
Print( temp )
temp = UnicodeAnnotationFromLib(0x300)
Print( temp )
Print( " done annotation" )
