OpenPrinting
Fixes web UI for non-existing printer/class
Fixes Issue #423 : When user open the api for any unknown classes or printers, then previously it was showing a random UI with that printer/class name. Now it will throw "404:NOT FOUND" error for those cases. Example for : http://localhost:631/classes/testclass or http://localhost:631/printers/testpriner
@tillkamppeter , Please check this pull request and suggest if some changes are required.
@michaelrsweet I have changed the templates file of classes and printers such that whenever someone directly enter web address like : http://localhost:631/classes/testclass then if there is no class with name "testclass", then that web address will render "ERROR: NO CLASS FOUND". Similiar will happens in case of printers. Previously the above web address was rendering unavailable class with name "testclass" which do not even exists.
@tillkamppeter , please review the changes, this time I have undo all the changes that were made in .c files and I have changes two templates , "class.tmpl" and "printer.tmpl" to solve the issue.
Oh sorry, I think comments are removed by mistake, and that file might be created due to my code editor's fault., these things do not have to do anything with solving issue. Wait, I will resolve these stuffs and with commit the final change again.
