disable "image upload blocking" on image jio save (probably it wrong)
use modified jio_putAttachment to save image:
* if attachId undefined then attachId = mimeType,sha1hashOfFile
* not save in jio storage if attach with checksumm already exist
* return attachId
* allow dataUri instead blob
use modified jio_getAttachment allow get attachment as dataUrl or
blobUrl (ooffice use blobUrl)
fixed double loading of textures

This fixes commit 63b3ccda

This allows to have some information when testnode fails running a test suite

Now the test node sends a  `--frontend_url` parameter to the test suite, which an IPv4-enabled URL to the test node's backend. This is required to run remote tests on environments without IPv6 connectivity. 

Also the SlapOSController now waits 20 seconds instead of 10 seconds for the SlapOS proxy web server to start answering requests. On slower machines 10 seconds weren't being enough.

@Tyagov, please review.
