Changelog:
===========
-Fixed issue where server default compare would not work for string defaults
that contained backslashes, due to mis-rendering of these values when comparing
their contents.
-Implemented basic server default comparison for the Oracle backend; previously,
Oracle's formatting of reflected defaults prevented any matches from occurring.
-Adjusted SQLite's compare server default implementation to better handle
defaults with or without parens around them, from both the reflected and the
local metadata side.
-Adjusted SQL Server's compare server default implementation to better handle
defaults with or without parens around them, from both the reflected and the
local metadata side.
