Improved doc lib extensibility

* doclist.lib.js now has an overridable "doclist_getAllNodes" function that makes it easier to reuse doclist.lib.js and its "doclist_main" method
* DefaultDoclistDataUrlResolver now has a basePath parameter so its possible to redirect doclib rest calls to a custom repo webscript using only config
