Problem when load font failed

[Ang Bodhi <angbodhi@pacific.net.sg>]

Hi,

In SoText2.c++ and SoText3.c++, when no font (not even the default
Utopia-Regular)
are loaded successfully, some variables will be left unintialized, eg.
bitmapDict,
which when reference later will cause core dump. I encounter this
situation when
using libFL wrapper to FreeType and no TrueType fonts are found.

The following changes continue the initialization even when no fonts are
loaded.
In SoText2, the no valid font situation are also deteced by checking
fc->fontNumList.
