Misc. bug fixes

[Ionic]

This PR bundles a few bug fixes, namely:

• fixing build.sh to include *.dtd files and generally keep the shell from interpreting file names, so that zip handles them correctly
• fixing inverted logic when parsing links with a comma in the presentation layer (js/mailhops_details.js)
• syncing up version number in js/mailhops.js and manifest.json

There are more things to come, but I'll PR them as we merge things!
