[Phamm] [PATCH] phamm-0.5.15: add <img alt="ON|OFF"> for on/off attribute display

[kabe at sra-tohoku.co.jp]

Pardon for patch in chunks...

When showing a boolean attribute, the TRUE.png/FALSE.png mini icon
didn't have any label for <img alt> HTML tag attribute, which made it
impossible to know the current value on a text browser. 

(N.B: elinks is usable, lynx is not, due to difference computing the URL
 from <A href="?action=..."> relative URL)

The patch will add the alt= attribute.

The alt="value" should have been escaped with htmlspecialchars() for safety,
but since other parts of the code doesn't, the patch 
follows the current convention.
