Use WP XMLRPC Method for getRecentTitles

Modified the getRecentTitles call to use the native Wordpress XMLRPC call rather
than the mt call that was used previously.
Use WP XMLRPC for Post Deletion

The output for post deletion has also been modified to provide a bit more
feedback.

Bumped the version to 1.2.0
Changed Upload file to use WP XMLRPC

Used to use the metaweblog XMLRPC call, now it doesn't.
Add Backwards Compatibility with pre 3.4 Wordpress

Modified the latest changes so that if a call to the newer WP XMLRPC methods
fails, then it falls back to the older XMLRPC API methods.  This should make
sure that blogtool doesn't break with older versions of Wordpress.
Further Wordpress XMLRPC API Updates

The getCategories and getPost methods in the xmlproxy module now attempt to use
the Wordpress XMLRPC API before falling back to the older methods.
newCategory now uses Wordpress XMLRPC API

The newCategory method in the xmlproxy module now attempts to use the new
Wordpress API before falling back to the older method.
Update addCategory to Wordpress XMLRPC

The newCategory method in the wp_proxy module now uses the updated Wordpress API
and falls back to the older one if it fails.
Code Cleaning

The recent mods to support the Wordpress XMLRPC API created some cruft that was
unnecessary.  I've gone back and cleaned this up where appropriate- removing
unnecessary private function calls and the like.

Some minor bug fixes in the upload function as well.
