Version 0.90: minor cleanups

Version 0.90 of sieve-connect is now available.

Checksums below, detached PGP signature available.

There are two changes since version 0.89:

• Update various regular expressions to not break under a future Perl 5.30 release;
• Use a .sieve filename extension for temporary files, to assist text-editors with mode selection.

This release is being cut because it's been a while since the regexp fix went in and we should get a proper release out before the next Perl comes along.
