Make TriggerEventController accept both 'channel' and 'channels'.

This is just a backport of a small part of commit fb958fb

It should fix #1041.

The same issue is also reported in pusher/pusher-http-php#351.

@mpociot can you look at this?

[adriangornypl]

LGTM :)

[madpilot78]

BTW I think a new release of the 1.x branch should be created afterwards, so this "fix" is available to everyone.

[adriangornypl]

Definitely a good idea :) Waiting with fingers crossed ^^

This is going to take more time than you imagine

• Ensure that the request has a valid signature
• If there is only one channel, it will be wrapped in an array to make sure we can iterate over it later on
• Iterate over all channels and broadcast the event to everyone except for the sender of this request

[tomvo]

can this merge be tagged with a new version?

@mpociot Can we expect a new release of 1.x with this fix soon ?
