Title: Support for: Alter table add index 

Alter table now handles the addition of indices. The following statements are now supported:
"ALTER TABLE c ADD INDEX idindex(id)"
"ALTER TABLE c ADD CONSTRAINT idindexconst INDEX idindex(id)"

As the constraint name is not handled anywhere the indices can be dropped by:
"ALTER TABLE c DROP INDEX idindex"
