Delete site by ID method tries to get the site_id from a query parameter rather than a parameter in the path

[tmcw]

In this line:

plastics/api/handler/site.go

Line 121 in 25854c6

id, err := ctx.URLParamInt64("site_id")

This is looking for a site id like ?site_id=… rather than the URL path of /sites/{site_id}. Right now I can work around this limitation by doing /sites/20?site_id=20 but the code should be adjusted to handle a URL parameter instead.
