artAttrCtx is undoable, queryable, and editable.

This is a context command to set the flags on the Attribute Paint Tool context.

Flag can appear in Create mode of command	Flag can appear in Edit mode of command
Flag can appear in Query mode of command	Flag can have multiple arguments, passed either as a tuple or a list.
