#4 Spanish charset in dictconv

[Diego Celso]

Some babylon dictionaries can not be converted because all charsets that support babylon are not inserted in dictconv. In my case I tried translate spanish-english dictionary and the charset type number that dictconv read is "20". babylon.h only have 14 type number so in my case it crashes.
For fix it temporaly i have fixed the babylon.c as i comment now.
I have replaced the line 148 for this other:
//if( type > 64 ) type -= 65;
// temp fix while bgl_charset cannot support all charsets
if( type > 13 ) type = 0;
