#34 Error recovery for HEAD method

[Gordon Weakliem]

AmphetaDesk uses HEAD to determine if a feed has
changed. If your weblog software doesn't support
HEAD, AmphetaDesk will never show updates to your
feed. It seems to me that if your server sends back a
405 (Method Not Allowed) or 501 (Not Implemented),
AmphetaDesk should try again with a plain GET. It could
even flag the feed to indicate that HEAD doesn't work
on that server.
