Fixed count bug in Doctrine_Pager that was wrong counting the total of results found. Added 3 new methods: Doctrine_Pager::getExecuted (checks if the Pager was already executed), Doctrine_Pager_Layout::execute (handy access to execute Pager query without having to access Doctrine_Pager instance) and Doctrine_Pager_Layout::processPage (processes the template of a given page and returns the parsed string)

reverting the reorganization done in 3455-3456 in order to make merging my experimental branch to trunk easier.

Preparation for new organization of code in to sub packages. Changed autoload() to work with new structure.

Added new exception classes, renamed Doctrine_Repository to Doctrine_Table_Repository, refactored many classes

removing the closing PHP tags form all php files, it\'s not needed and can break sessions which are whitespace sensitive
