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

when using Doctrine::compile(), having the require_once()'s in the source files will break things. This is because the file hasn't been included, but the class has been defined in the compiled file.  This means you have to rely on autoload to allow compile to function (or strip out all require_once's from the code on compile, but atleast one needs to be maintained). IMPORTANT: you MUST now use autoload.

Added Doctrine::tableize(), Doctrine::classify() and DataDict::isValidClassname() for proper table naming. Fixed Table() to accept these (more need to be changed such as rawsql).Also fixed unbind method (missing argument)

Many-to-Many relation fetching, fatal proxy state bug fixed, fatal loaded identity map + multiple component fetching bug fixed

Doctrine_Table::find now returns false if record is not found (instead of throwing InvalidKeyException)
