[gs-code-review] CET 23-13-04, Font dictionary differences

[Alex Cherepanov]

Require resource category to be a name in the findresource operator.
Convert 1st operand to a name when it's a string.
Partly fix CET 23-13-04.

Differences:
None: no CET or comparefiles differences.

The content of Courier font directory is still different.
    Ghostscript has /.Alias and /PathLoad
    Tek has /FontType 14, /CharOffsets, /GlyphData
    Distiller 5 has /CharOffsets, /DistillID
    PhotoPrint has /CharOffsets

The values of UniqueID, XUID, the length of CharStrings and Private
is different too.

Please review my decision to consider there differences as acceptable.
