Set version to 0.2.8 after merging 'install-dollarfiles'

Update version number because of previous (merge) commit. The
merge was done with github's 'Merge' button. Never again. The merged
commit was 49a0b2f from 2016-06-28 allowing installed files to
contain weirdo characters, and closing issue #19.
