wlw_blogapi 6.x-1.1

Changes since DRUPAL-6--1-0-beta4:

• remove use of excerpt as url_alias, enable slug and url alias.
• html entities were escapes when titles were submitted by WLW. Actually they were doubly escaped. I adjusted the wlwmanifest.xml file to disallow html in titles, so titles are in plaintext, this is preferable.
• if there is a vacabulary assigned to the node type that allows free tagging: categories added in WLW will be added to this vocabulary
• commented out a couple of watchdog debug commands that are no longer necessary
