[V4MD2] Using collation strength

[Heinrich Ruoff]

Made some tests using collation strength:

Create a database using sql-example IndexByWords, save it to disk and
open it again, then gDb.getCollationAttribute(#kStrength) reports
kTertiary instead of kPrimary, but case insensitive search using
SELECT and LIKE still works!

Create a database using loadDump and a previously exported sql file
with CollationStrength set to kPrimary -> case insensitive search
won't work!

any ideas?
