Fix getDocumentList setTimeout bug.

Redesigning JIO in order to use 'success' and 'error' callbacks instead of 'onResponse', 'onDone' or 'onFail'.

Dav can now get content with getDocumentList.
Conflict manager errors are managed better and more explicit.

The problem seams to not come from the crypt storage.

Tests works now on a virtual local storage

Only saveDocument is implemented yet, but it is not complete.

This storage will wait before executing command on another storage.
So there is a parameter "storage" (like indexedstorage).
Wait storage can have some optional parameters:
key     : default value
-----------------------
delay   : 5000,
save    : true, // will wait 5 seconds before saveDocument
load    : false, // won't wait
remove  : false, // ''
getlist : false. // ''

Jio jobs now knows what to do if eliminated, updated or not accepted.
We can make DummyStorageAll3tries be different from other similar storage by
adding some useless parameters. So older similar storages won't be replaced.
Correcting some bugs in replicatestorage.
Adding one qunit test (jio does not pass it...)
In intro.js, `var log' is used for debuging.
Better applications managing in OfficeJS.
