Fix parsing of imap.preformattedHTML and imap.sslverify

These two variables are boolean and can lack "= value" in the
configuration file.  Do not reject such input early in the
parser callback function.

Also the key are downcased before being given to the callback,
so we should run strcmp() with keyword spelled in all-lowercase.
