Fix bug in climatology selector in Data

* In most cases no climatology was returned when using Data::getClim

Specify input filename formats more flexibly

* The standard date format (%Y, %m, %d, etc) can be used to specify the
  format of the filenames for an input.

* Input::getDates searches for dates within a preset date window. The
  date range can be specified using options 'startDate' and 'endDate'.
