Re: [xwiki-devs] Resolve/Serialize entity references on the client side (JavaScript code)

Hi devs, While fixing http://jira.xwiki.org/browse/XWIKI-7889 I introduced an API to resolve and serialize entity references on the client side (JavaScript code). See https://github.com/xwiki/xwiki-platform/commit/cfa8ec3315a32fed875949ff21a5…. XWiki Explorer tree has an input displayed at the bottom where you can type a _pseudo_ entity reference which is parsed and the specified entity is selected in the tree. The basic problem (very simplified) was that this reference was parsed on the client side and the parsing code did not handle special characters in entity name (no escaping). Of course, I had to options: * add a service (REST?) to resolve/serialize the reference on the server or * (as I did) port part of the code from xwiki-platform-model (with unit tests!) to JavaScript to be able to resolve/serialize entity references on the client side. There are pros and cons for each option but for me the main reason was that it is painful to modify xwikiexplorer.js to make AJAX requests each time you type into that input box (the tree node is selected as you type). An almost complete rewrite was needed and since we're looking to replace that tree I thought the second option was better. Would be great if you can review my commit. I'm interested in the API naming and places where I put the JS code. Also, I'm not sure where to document the new API (that is if no one is against it).
