gg Webservices 0.4 released

Lots of new features and 2 bug fixes in this new release:

• added support for calling external services that require simple POST (a.k.a. html forms) to the template fetch function / ggeZWebservicesClient class
• added a view to invoke webservices without the need of a specific controller file: /webservices/execute/$protocol (supported protocols are currently xmlrpc and jsonrpc)
• permissions to execute - with limitation on single webservices - can be granted on that view
• add support of exposing ezjscore webservices to xmlrpc/jsonrpc calls via that view
• added the Y.io.jsonrpc javascript function for Yui 3 (in module 'io-jsonrpc') to ease execution of jsonrpc calls from the browser
• moved javascript libraries to 'standard' design, so that they can be used for front-end interfaces too
• added a cronjob to rotate logs of executed ws calls. By default added to infrequent set
• upgrade the included phpxmlrpc lib to 3.0.0 beta, fixing all warnings with php 5.3
• webservice server classes now catch exceptions raised by user-provided functions while handling invocation calls; use the server's $exception_handling member to finetune this behaviour
• allow module view (and custom controllers too) to load all functions in soap/jsonrpc/xmlrpc dirs regardless of the incoming call's protocol. Set RegisterAllProtocolsFunctions=enabled to activate
• fix: give a debuggable error message if soap extension is not enabled and user tries to create a ggPhpSOAPClient
• fix: bad php constants where used by ggXMLRPCServer if invalid params where received

There have veen a couple of incompatible changes too - please read carefully the changelog before upgrade.
