htags improvements.

[Bakken, Luke]

Hello,

Attached is a diff containing some changes I've made to htags.
Specifically, htags now runs under "use strict;", which is pretty
conventional. On a small source site, it shaved an average of 2 seconds
off of a 23 second web site build time.

I also have updated the syntax to reflect more contemporary (and
correct) perl coding style, and have made a small change to the anchor
package. The anchors are stored as array references in the ANCHORS
array, which eliminates the need for so many split() calls in that
package.

Thanks for a great software system! I couldn't work productively without
it.
Luke Bakken
