cleanup of apidev functions

[funderburkjim]

There are some functions, class methods, etc. that are no longer used. These should be removed so they don't clutter the current code base.

getword_data_html

This is in module getword_data.php.
It was written when precomputed html was being used; as mentioned elsewhere, precomputed html is no longer used in the apidev system. In particular the getword_data_html function is called nowhere. So, this function can be deleted.

Note: The function getword_data_html_raw is used instead.
This function is called only by modules getword.php and servepdf.php.

get1_basic

This method of class Dal (in dal.php) is never used. Hence can be deleted.

getword_data_html_raw -> getword_data_html

Now that we got rid of the unused 'getword_data_html' function in getword_data, we can rename the
getword_data_html_raw function to just getword_data_html -- no need for the '_raw' suffix.

This requires changes in

• getword_data.php where function is defined
• getword.php where function is called
• servepdf.php where function is called.
