Minor document changes.
Fixed cosmetic variations in how lists (and vectors) were printed so that the unit tests pass.
Fixing a defect that meant that reading expressions starting with a closing keyword (such as endif) put the common2gnx parser into an infinite loop.
Adds exploder to the variables that record definition makes. Also makes "field" a synonym for "slot".
Fixed the use of atomic expressions in elements.
Found a couple of bugs in the functional tests for elements. Fixed and bumped the version to alpha status.
