Backwards incompatible v2.
Support for user configured API's.
URLs could be passed as full or as suffixes to configured endpoint.
Still supports external callers and parsers, but also doesn't required to instantiate built-in by hand.
Magic methods for callers ->*Call().
Changed profile page design.
No longer opens separate page to show data.
Request and response headers are available in the profiler output.
Results of the API calls were never actually returned to the user.
Bugfix: it wasn't possible to actually pass a custom parser.
Parameters could be omitted when initializing CurlCall
Parsers are now callables.
onetimeParser added (it resets to default after next call).
onetimeEngineOption added (it resets to default after next call).
ApiCallInterface (and so CurlCall) now accepts $url, $command and $parameters instead of just $url and $parameters.
Rpc caller.
Xmlrpc parser.
Engine configuration variables now could be something else, except for scalar.
