Allow absolute paths

[essemme]

hello, I had problems on my production server with relative paths - so i made some quick changes to allow absolute paths in config / tinyMce init, like this:

    open_manager_upload_path: '<?php echo $_SERVER['DOCUMENT_ROOT'];?>/uploads/',

(don't know if this is needed too - it probably is:

    relative_urls : false,

)

it's just a quinck patch, not fully tested (it works for me, so it was enough at the time)

Some refactoring might be needed. But sharing anyway is probably better than keeping it for me :)

Hey Stefano this seems great, will do some testing on this before making live but more than happy to include this improvement ;)

Great - Hope I did't break anything in the rush :)

(by the way, i forgot: thank you for sharing this)

Thanks no problem :) Still need to check through this but thanks again for your help!
