Change emission rate type to calendar day, in alignment with the fuel rate which is also calendar day.
Update documentation with info about changing name from direct emitters to venting emitters. Both keywords will exist in the documentation for a while, with a description of which keyword is valid for which versions of eCalc.
Change name from DIRECT_EMITTERS to VENTING_EMITTERS in input Yaml-file. Using DIRECT_EMITTERS will not cause eCalc to fail (this will change in a future version), but no output will be given for the actual emitters if the deprecated keyword is used.
