replaced 2-part Git version with just log count, split date from detail in gitlog view

added app version from git and gitlog

synchronised with D2-plugin-db version: completed edit/update functions, added tests for same; adjusted date for localtime

reversed previous fix for init_db.sql schema, sqlite3 can execute multiple statements, failure in previous versions probably due to syntax error in users table insert statement; new routes.t file omitted from previous commit
