texture_font_get_glyph may create multiple glyphs of char code -1

[GoogleCodeExporter]

Working base r108

Each call of texture_font_get_glyph with char code -1 will create a new glyph. 

Because the check of loaded glyphs :

        if( (glyph->charcode == charcode) &&
            (glyph->outline_type == self->outline_type) &&
            (glyph->outline_thickness == self->outline_thickness) )

compare not only charcode but outline_type and outline_thickness. But the 
creation of the glyph of char code -1 dose not initialize outline_type and 
outline_thickness.

Thanks, I've committed a fix that discard outline type/thickness for glyph -1.
