HTTP-related commit...
Adding support for HTTP requests with 'if-modified-since' headers: for static files. The 304 Not Modified should be returned for static files (at least since the time the server is started -- as it caches the contents anyways upon the startup).
Subsequent shortening of caching for the owned-static-files (to 30 minutes cache-control max-age), the zip libs (i.e. third-party ones) are still at 48 hours (due to extremely low likelihood of being changed).

Introducing (not fully tested yet) support for Chrome. Subsequently some changes/bug-fixes were done (regex octal char range specification in csv parsing, postMessage transferable object support/lack-thereof). Note: chrome support is being added due to the fact that it is available on iOS (iPhone/iPad)... explicit support of Safari is unlikely until the actual hardware (Apple laptop/computer) becomes easily and readily available for prolonged development and testing usage.

Additional compatibility "bug"-fix (even w.r.t. previous verisons in Firefox): removing function declarations with default arguments. e.g. function blah(a, b = ""), now the caller must supply every arg explicitly: blah(1, "aeou"), blah(1, "") and so on.

Bug-fix in http/server.cc -- body boundary, etc. were converted-to, dealt-with-as, lower case... not cool.
