Merge branch 'master' of http://pine--is.grid.private.cam.ac.uk:8888/gitlab/rs481/Ethiopia-EWS-Coordinator

Moved the csv files of manual removals and additions from coordinator directory to workspace directory

Corrected manual-entry survey data for July and August 2019 where stem and yellow rust data had been incorrectly switched.

Bugfix: maintainersAll list was being created incorrectly (thanks to an online perl example being wrong)

Bugfix: Handled edge case where runs could become stuck if FTP goes down before the time at which warnings start to be issued. Bugfix: Corrected calculation of data availability/warning times. Added more structure to the inProgressFile handling. TODO: Deal with TZ/UTC offset around midnight causing spurious warnings. TODO: Check warning emails are always successfully sent

Following input from MO, data could become available from 0800 (if there is an error), but actual output will be slightly later than previously configured values.

Added new server checking behaviour from DataProcessor.pl to ENVDataProcessor.pl and harmonized scripts. Initial data acquisition from server portions are now identical (again) and the repeated logic should be separated out into a utility function in the future

Bugfix: Supplied server name in error string.\nFeature: (in last commit) automatically email the met office when data is obtained, but either the zip is empty, or does not contain some of the necessary files

Feature: NAME data processing script handles FTP server outages more gracefully - will keep retrying if the server goes down, and only warns if the server is down around the time data is expected. Additionally, the script will issue a warning if the data is not available by a specified time (irrespective of whether or not the FTP server is available).
