new build SQL features

[adamfoneil]

Under the Build SQL menu, let's add a couple generators:

• param declarations (for an insert statement/proc, with types and optional null args)
• param values (just a list of columns with "@" in front of each)

with options to

• put the comma at the beginning or end of lines
• use "column alignment" of types

The formatting options should be extracted to higher level so they can apply to other generators. There should be options for single or multi-line. Should be an option to preserve table definition order or separate into required/optional columns.
