[dojox] rename _sql to sql

[dante]

the _sql project breaks a few dojo conventions (or at least the de facto way of doing a dojox project) ..

_sql/ needs to be sql/ and only mix into the dojox.sql namespace common.js needs to be _base.js

this poses a small issue with the use of dojox.sql = new Function, which can be avoided with Neil's "bling" method (more or less)

(In [14596]) refs #7294 - moves _sql to sql -- broken until next checking, which will rename common to _base, and make work again. !strict

(In [14597]) fixes #7294 - make root code for project match naming convention of DojoX !strict

[dante]

(In [14598]) refs #7294 - add an dojox.sql project rollup file ... perhaps we should have a dojox.profile.js that does this for each of the projects to optionally build rolled/optimized versions of each project individulally.

(In [16987]) fixes #8821 #7294 #8758 focus is now visible on column header cells of empty grid; tab and shift-tab work to navigate thru editable cells once in edit mode. !strict

sorry, was already closed by [14598] I'll just leave it that way and go away now.
