Fixed formatting of README.md
Added &send_report subroutine and added EmailServer, EmailFrom and EmailTo configuration parameters in dhcr.conf
Instead of merging the subroutines to query Reporter and ESL as per commit 8db5c055be66c649fe4cd4c5e7c163b24ef7df99, now we have a subrotine for each type of query &select_faulty_reporter, &count_all_reporter and &select_all_esl
Subroutine &populate_db is responsible to insert data from ESL and Reporter into the DHCR's SQLite database
Inserted &calculate_percentage subroutine. Changed the name of database subroutines to look like the query they execute e.g. &select_faulty_from_reporter.
Changes in template.html: inserted variable values using HTML::Template and changed the layout a little bit. Inserted subroutine &generate_report to populate the template. Inserted parameter ReportsTemplate in configuration file to specify the HTML template to be used.
