gives ability to custom url shorten provider

[wilsonlmh]

It's a small upgrade gives ability to custom url shorten provider with following config:

config:
customUrl : the url will wrap with sprintf(), use %s as the source url, example http://shorten_server/add?url=%s
customJSON : extract value in JSON for returning, example: ->response->shortedURL note: '->' is required for array, this gives ability to access root level of JSON.

It use curl on server side to query the provider(it good for local server, more secure). I haven't test it yet bcoz im still working on my shorten script. However I don't have experience on writing owncloud plugin. Can you please help to do a fast review on it? Thanks!

I tested with some code correction, however it doesn't works.
Since I never write owncloud plugin before, I can't figure out where $_['xxx'] came from in /templates/admin.php and it cause error and stuck everything. :'(

OK I figure out this, but something other happen: an error from log:
Array to string conversion at /var/www/sites/cloud.server4.home.luniz.info/lib/private/template/functions.php#36
However I don't know how to trace the issue bcoz i dun know how to debug in owncloud@@

OK, the problem is about cross-origin now
My server is rewrite behind a front-end server(honestly, that's bcoz i dun hv a physical linux server). And I'm using radius-auth plugin with the tricks described here(add a require statement):
https://forum.owncloud.org/viewtopic.php?f=3&t=6543
The radius is works fine seems not a issue from there. And here is my debug log(I replaced my domain name):
