Minor changes

noticed that RawPageSqlDao has a method getAllRedirects, which should really just implement using a get(DaoFilter) call, so I deprecated it and replaced the usage.

Also modified all the get(DaoFilter) methods so that if they are called with an empty DaoFilter, they will return the entire database

All tested, and everything still works

Also edited the language option in Env to specify hasArgs() and getValueSeparator(',')
