string to vifib master.

This reverts commit 0dedf0a5.
Vifib skin folder ordering has to be cleanly defined (priority=60 like for the
other skin folders).

There is no need to show SoftwareInstance_view.

Reorder the business template list on BusinessConfiguration_setupVifibStandardBT5 to match with vifib tests.

This reverts commit ba0006c9.

Additionaly convert all to JSON.

 * explain all common errors once
 * drop extension, as content type is good enough
 * make requests looking like real HTTP requests, define required headers
 * explain inline possible values

(Removing trailing space at the same time).

Avoid having two same gid.

Anyway such calculation result in wrong addresses.

Thanks to this error in one transaction will not stop other one.
