EE 2.6 compatibility

[tciny]

Attempting to install the module in EE 2.6 yields the following error:

A PHP Error was encountered
Severity: Notice
Message: Undefined property: Addons_modules::$channel_model
Filename: rsvp/mcp.rsvp.php
Line Number: 105

Fatal error: Call to a member function get_channel_info() on a non-object in /var/www/system/expressionengine/third_party/rsvp/mcp.rsvp.php on line 105

Can you try changing line 29 of mcp.rsvp.php from

$this->EE->load->model('rsvp_model');

to

$this->EE->load->model(array('rsvp_model', 'channel_model'));
