Added function get_cff_glyph_name() in order to facilitate getting a 

glyph name for glyph index via FT_Get_Glyph_Name().

In function cff_get_interface(), added support for getting a glyph
name via the "glyph_name" module interface (used in the function
FT_Get_Glyph_Name()).  We use the new function get_cff_glyph_name().
