cell: pack more efficiently and store glyph as a wchar

Browse source 
The 'attributes' struct is now 8 bytes and naturally packed (used to
be 9 bytes, artificially packed).

'cell' struct is now 12 bytes, naturally packed (used to be 13 bytes,
artificially packed).

Furthermore, the glyph is stored as a wchar instead of a char*. This
makes it easier (faster) to do glyph lookup when rendering.
