Print host when connection failure occurs

In the event of a mysql connection failure, it was not possible to
determine what host failed.  This change prints out the host as well as
the rest of the exception for easier troubleshooting.
Add FauxTruncate

http://bugs.mysql.com/bug.php?id=68184

Due to this, using "truncate table" can cause stalls within innodb.
Until this is fixed, FauxTruncate can be used.  It creates a duplicate
table, swaps it with the old, and then drops the old.
Bump version to 0.3.5
