- Move QuoteIdent() and DeQuoteIdent() out of TMySQLConnection, make them classless
- Remove TMainForm.mask(), instead always use QuoteIdent()
- Introduce a third parameter to QuoteIdent(): "AlwaysQuote" - setting this to false will quote only if required
- Set AlwaysQuote to false for all stuff which drops some code into the query editor, see http://www.heidisql.com/forum.php?t=6986
- Remove ensureValidIdentifier() and its partly uncatched exceptions. Instead, disable "OK" buttons for empty table/view/proc name.
- QuoteIdent and DeQuoteIdent now take the glue char instead of a "HasMultiSegments" boolean param, so they're more exact when "user@host" or "db.name" come in.
