2016-10-06/2016-10-07 mismatch

[glensc]

on 2016-10-07 git tag the plugin.info.txt date value is 2016-10-06: https://github.com/cosmocode/edittable/blob/2016-10-07/plugin.info.txt

i suggest adding some .travis.yml check to indicate about the failure when tagged build is made

https://docs.travis-ci.com/user/environment-variables/:

• TRAVIS_TAG: If the current build is for a git tag, this variable is set to the tag’s name.

here's shell script to extract the value:

version=$(awk '/^date/{print $2}' plugin.info.txt)
