new functions: pspell_new_personal(), pspell_save_wordlist().
pspell_save_wordlist() needs to be changed to return error-codes
once pspell library gets fixed
Added a few RCS $Id$ tags.
# Note: I have avoided changing any .h files if the corresponding .c file
# had not already been changed as I am not sure if there are any legal
# issues here. So some extensions still have PHP 3 headers.
