Bumping development version to v0.3.0.dev
Bumping development version to v0.3.0.dev

The latest merge into the dev branch introduced a major
package refactor and seemed worthy of a bump in minor
version number (hence, v0.2.26.dev to v0.3.0.dev).
However, there are still bugs to be worked out and some broken
packages that still need upgrading before merging these changes
into the master branch.
