Set a file that contains personal wordlist. The personal wordlist will be
loaded and used in addition to the standard one after you call
pspell_new_config(). The file is also the file where
pspell_save_wordlist() will save personal wordlist to.
pspell_config_personal() should be used on a config
before calling pspell_new_config().
Parameters
dictionary_link
file
The personal wordlist. If the file does not exist, it will be created.
The file should be writable by whoever PHP runs as (e.g. nobody).
