Thanks to Guillaume Royer <guillaume.royer@clearroad.io> for reporting
the issue.
See !103

Try to reproduce the browser specifications.

sinon now correctly replace it only on demand.

Do not spy XMLHttpRequest, as it is node 100% compatible between node and browser.
Spy ajax calls instead.

Do not rely on storage not available in node (like localstorage).

Deprecate websql.

Add group_by parameter to allDocs.

Queries: Fix some parsing/serialization issues

- fixes query toString inconsistent output
- change serialization behavior
  ( a:b OR a:c ) -> a:( b OR c )
  a:( b OR c )   -> a:( b OR c )
- rename simpleQuerySetKey to querySetKey
  as it also applies on complex queries.

Fixup linshare

Add LinshareStorage

LinshareStorage uses the linshare document name as jio key.

If multiple linshare documents have the same name, only the most recent modified is used.

Thanks to Vincent Bechu for his work on this storage.

Fix IndexedDB transaction handling.

Ease usage of ReplicateStorage.

Accumulate all operations done in a ReplicateReport object.

This ReplicateReport is returned by the repair method in any case (success or failure).

If an error occured while replicating a document, do not stop the full process and log the issue in the report.
Which means repair now always tries to replicate all documents even if one fails.

Each operation has a code to ease parsing it if needed.

By default, the report only contains error code (< 100).
It is possible to change the log level by using the 'report_level' storage parameter.

If the 'debug' parameter is set to true, codes will also be displayed in the console.log.

Open database is now wrapped into a promise which ensure that the database will be closed as soon as the promise is resolved.
This will allow to open multiple transactions if needed.

Transaction creation is now manage by a promise, which will abort the transaction if cancel is called.

The transaction will also be aborted if an error occurs during its callback function.

As transaction abort will reject all accesses, it is safe to use .then method inside the transaction callback.

Check the transaction error event to detect some browser internal errors (like QuotaExceededError).
Previously, such error was silently ignored, and the jIO client was not aware that the data were not correctly written.

All deletions are now correctly checked, and the method will wait for all deletion to be successfull before returning.

Improve putAttachment algorithm to make it update the previous value and delete only the useless blob chunks.

Reduce the usage of openCursor to not fetch the table content if not needed (like if the index key is enough for example).

Revert ERP5Storage local_roles handling breakage

This reverts commit 7e9921a4.

This change broke the ERP5Storage local_roles/worklist handling.

No need to publish development files.

Implement a basic FormData support, used to serialize the POST body.

Use xhr2 library to replicate XHMLHttpRequest.

Desactivate all broken storages (IndexedDB, localstorage, webdav, ...) which rely on browser API.

Thanks to Aurelien Calonne <aurel@nexedi.com> and Guillaume Royer <guillaume.royer@clearroad.io> for their contributions.

As the list of included storages is defined in the Makefile directly, force building jIO in any case.

Use a Makefile to concatenate the file (and so, drop grunt).
Allow to build without linting

Fetch external dependencies with curl.
As they are few, it simplifies the process.
Keep a local copy of the dependencies.

Add Jison call in the build process.

JSLint can be also triggered from the makefile, and installed how the developper prefers.

Drop the package.json, as jIO is for now not published on npm website.

Remove unused libraries.
