XWIKI-9320 REST objects api wrongly encodes property values
XWIKI-9435: Don't display the wiki filter if there is only one wiki
* The search filter looks bad with the wiki filter hidden to I change it to select the main wiki when there is only one wiki.
XWIKI-7883: document.get(property) displays key not value for a property of type database list which has key and value in multiwiki mode.

* Now, DBLIstClass#getDBList() executes the query on the good database.
* I have replaced xwiki.search() by QueryManager#createQuery() to not increase the technical debt.
* Bug fixed!
XWIKI-7993: documentAccessBridge.getAttachmentURL(AttachmentReference,true) not returning the FULL URL
* reverting XWIKI-5917 (html export is broken for images), please find a better idea than breaking an API
XWIKI-9428: Missing translation keys for the parameter "columns" in the "Documents" macro
XWIKI-9437: Fully allow using XWiki when cookies are turned off
* Note that there's a lot of work in verifying that all places that generate URL use response.encodeURL as on the Macros.xml page that I fixed. Ideally there should be a common service used to build URLs like XWikiServletURLFactory (but this one only handle Entity URLs).
XWIKI-7883: document.get(property) displays key not value for a property of type database list which has key and value in multiwiki mode.

* Apply Thomas M suggestion.
