Fix for TextMorph emphasis

[Chris Muller]

Today I noticed a new bug; persisted TextMorphs were always
materializing with the default font.

TTFontDescriptions are canonicalized into a class var, with each image
potentially having a different set of fonts.  Magma doesn't reinvent
the wheel; employing the built-in System behavior, the DiskProxy
mechanism to, upon materialization, lookup the font by name and, if
not present, use the Default.

The problem was two-fold.  First, "Ma object serialization" was
incorrectly looking it up by #fullName, instead of #name, causing the
Default font to always be used.  Second, the base Squeak 3.9 image
somehow lost all but one of the cached TTFontDescriptions from 3.8.
The attached file-in will simply restore these (from allInstances, of
which there are exactly 10 in 3.9).

After these two fixes, my TextMorph fonts are now correctly being
identified and used.

This will, of course, be integrated into r41.
