Allow user to omit font size specification when loading a font. In addition

the following fixes had been made:

- check the size of the font being loaded and compare it with possible sizes
  to minimise possibility of loading something that is not a fontfile at all
  and turning console screen into garbage;

- prevent buffer overflow (and coredump as a result ) when loading valid
  uuencoded file with size that exceeds allocated buffer;

- correct and improve several error messages.
