Split into smaller SECTIONs

[Rangi42]

Some banks have many pieces of independent code or data, which could all go in their own SECTIONs with less generic names than "bank1", "bank2", etc. They don't have to be as finely subdivided as possible, e.g. a SECTION "Tilesets 1" is fine even if the individual tilesets in it are independent, but for the large SECTIONs of miscellaneous engine code this could be helpful.
