* WireClient Interface
* --------------------
*
* This file exposes a get/put/delete interface on top of XMLHttpRequest.
* It requires to be configured with parameters about the remotestorage server to
* connect to.
* Each instance of WireClient is always associated with a single remotestorage
* server and access token.
*
* Usually the WireClient instance can be accessed via `remoteStorage.remote`.
*
* This is the get/put/delete interface:
*
* - #get() takes a path and optionally a ifNoneMatch option carrying a version
* string to check. It returns a promise that will be fulfilled with the HTTP
* response status, the response body, the MIME type as returned in the
* 'Content-Type' header and the current revision, as returned in the 'ETag'
* header.
* - #put() takes a path, the request body and a content type string. It also
* accepts the ifMatch and ifNoneMatch options, that map to the If-Match and
* If-None-Match headers respectively. See the remotestorage-01 specification
* for details on handling these headers. It returns a promise, fulfilled with
* the same values as the one for #get().
* - #delete() takes a path and the ifMatch option as well. It returns a promise
* fulfilled with the same values as the one for #get().
*
* In addition to this, the WireClient has some compatibility features to work with
* remotestorage 2012.04 compatible storages. For example it will cache revisions
* from directory listings in-memory and return them accordingly as the "revision"
* parameter in response to #get() requests. Similarly it will return 404 when it
* receives an empty directory listing, to mimic remotestorage-01 behavior. Note
* that it is not always possible to know the revision beforehand, hence it may
* be undefined at times (especially for caching-roots).
