Andrej Stieben db949bb802 Updated modules to allow for partial overrides without errors
Only define functions if they have not been defined before, e.g. in themes. This makes it possible to override parts of a module and still use the other functions.

/**
*
* This is the POST destination for most all locally posted
* text stuff. This function handles status, wall-to-wall status,
* local comments, and remote coments that are posted on this site
* (as opposed to being delivered in a feed).
* Also processed here are posts and comments coming through the
* statusnet/twitter API.
* All of these become an "item" which is our basic unit of
* information.
* Posts that originate externally or do not fall into the above
* posting categories go through item_store() instead of this function.
