[wp-xmlrpc] Patch to trim whitespace from description/more

[Daniel Jalkut]

There are a variety of little problems with the way XMLRPC in WP  
currently literally interprets the description and mt_text_more  
components of a post cargo.

The rest of WP is strongly biased towards trimming these components  
such that there is no whitespace between them and the separator "\n<!-- 
more-->\n".

Because XMLRPC currently crudely combines the two components with the  
separator, you can end up with unwanted whitespace in the database,  
which further confuses things in the rest of WP.

I propose to trim these components so that submitting a post from a  
remote client will result in the same massaging of the content that  
entering the post from wp-admin experiences.
