Vulnerability in light client proxy (#1081)

Browse Source 
* Vulnerability in light client proxy

When calling GetCertifiedCommit the light client proxy would call
Certify and even on error return the Commit as if it had been correctly
certified.

Now it returns the error correctly and returns an empty Commit on error.

* Improve names for clarity

The lite package now contains StaticCertifier, DynamicCertifier and
InqueringCertifier. This also changes the method receivers from one
letter to two letter names, which will make future refactoring easier
and follows the coding standards.

* Fix test failures

* Rename files

* remove dead code
