[yaala] some patches to 0.5.3

[Макс]

q0-fixes: minor fixes of typos and some strange bugs,
          added field 'indent' into squid report;

q1-decor: fixes in .css and HTML - were bogus in some browsers;

q2-input: input method module.

only 'File' implemented.
/* 'Dir' was too bogus, i'll rewrite it later... maybe */
The scheme is simple, but maybe not the best:
parser module should load proper input module it whish work with,
if it don't, yaala loads default input module 'File'.

And then it calls input:::open, input::fetch, input::close
for each filename (or whatever it is for other input sources).
