moved dpw categories from tt into db

added date field to dpw dataset; documented deployment on ZBOX using lighttpd

extended app to provide household/dpw function; provided session expiry time display; increased dev env cookie_duration (but session still times out too early); sync'd InfoLib & Moongate save_document() methods with DPW class (using global @cols)

search function returns to home page instead of summary if no records found

bugfixes after previous commit

major rewrite - combined separate docs-lib and moongate apps into single app using prefixes with multiple route files; merged DB functions into model which is now a D2 plugin, providing encapsulated model domains (infolib, moongate & dpw); uses route names to allow tt to call uri_for_route, but some caveats: * route names must be unique across all route files * uri_for_route cannot be used in any template loaded after a forward since the data required in request.uri_for_route($name) is deleted during the forwarding process leading to fatal error when tt calls the uri_for_route function; META function no longer works since tt WRAPPER function disabled to allow routes to define layout

disabled TT WRAPPER to allow layout to be defined in routes; bugfix - apphandler setting not available in tt so default index.tt cannot diplay value, needed to add as a token

changed search view to summary page

bugfix & omissions

made search function case-insensitive

new function /summary, to replace 'all_docs' on footer

fixed dbix 'on-connect-do' schema - 1st production run of Moongate failed to process 2nd and subsequent statements

re-instated original default index route

removed keywords as a function, they are redundant as search covers title and contents, keywords provides no additional value

changed $cols to $fields in App::DB to disambiguate from @cols; cosmetic change to gitlog() method for brevity; root ('/') route needs to capture query_param when forwarded; tests need cookie_headers for routes recently protected by authentication
