git ignoring widetsets
Added a dummy test so Git saves the test folder in the orient project
@Ignore TestBench tests pending licence selection
Removed test results, except test summary, updated .gitignore to store
only test summary.  Fixes #203
Git having problems with a single summary test file nested a couple of folder deep.
Ended up in a loop with Git offering to commit changes in order to switch branches
but no changes to commit.  Not worth trying to solve, removed all test results.
Removed WebContent folder from demo, not used by Gradle
Removed vaadin.* prefixes inside the vaadin closure of build.gradle
files.  Removed remaining test summary reports
Testbench tests re-instated
Updated README.md
