ANN(again): slightly newer tools added

basically, same site as last tools, and same thing.
ok, I have made some adjustments to the tools (fixing some bugs, ...), and I
have also made some minor adjustments to the format (should not effect
archives made by the last one, but I haven't really checked).

in particular:
fixed some broken command line options related issues;
the default frontend now behaves a little more like gzip/bzip2 (some similar
command line options, though does not delete originals);
default frontend now prints a lot less stuff to screen by default.
made some ajustments, eg, the dictionary size is auto-adjusted for small
files;
...

I also added an "htar" tool, which is an archiver with an http-like file
format.


issues:
speed could be a lot better (it is presently quite slow);
compression ratio could use some improvement;
I will blame both of these issues on crappiness in the hashing algos, and
also on the memory requirements;
...

some other things I am still considering/wondering about, eg, possibilities
for trying to sort matched strings and lookup in a smaller number of steps,
whether I should add the current bit number to the byte contexts (testing
shows an increase in ratio, but I haven't really justified if it is "worth
it" vs, say, just increasing the number of context bits).
