[CB-1494] weinre - Supports running server behind a proxy, such as Heroku Cedar

https://issues.apache.org/jira/browse/CB-1494

Easiest thing to do is just neuter the remote address check in
the getChannel() function in the weinre.server/lib/channelManager.coffee
source file.

All this provided before was a simplistic check to make sure the
requests always were coming from the same remote address; for
someone who wanted to cheat, there were ways of cheating, and so
still are.  For everyone else, you can now run under proxy servers
transparently.
