phpAds - 1.3.0 -> 1.4.0

Version 1.4.0 is not 100% compatible to version 1.3.0.

The syntax of the view() call in local mode is downwards compatible. 
With remote invocation, a new argument ("n") was introduced to allow
multiple remote banners. The syntax with remote invocation remains 
downwards compatible to 1.3.0, though.

New tables and new fields in existing tables have been introduced. It
is recommended to reinstall the tables completely, and to add your
banners from scratch. 

If you want to preserve your old banners, you may be able to do the
necessary changes manually:
The table clients has one new field, which you'll need to add manually:
   expire date DEFAULT '0000-00-00'
The table acls is new. Please don't go this path on a production 
environment without further testing.

Attention:
Updates, Upgrades, and changes should never be performed in a 
production environment without careful testing on a staging server.
