SQLite does not have CHAR_LENGTH or CONCATENATE functions

While working on unit tests in the CMS, I ran into issues with the SQLite query builder in that it was using syntax for CHAR_LENGTH and CONCATENATE functions that aren't supported in SQLite (at least with those names).  This PR implements overriding methods to add the appropriate support.

Also, the coding standards submodule was showing an update in my local, so it's lumped in here.
