Fixes#1411 and the subsequent refactoring fixes#1551 as well.
mostly issues around uninitialized variables, calling non-static
functions in a static context, calling Session functions directly
instead of on its singleton, passing non-variables by reference, and
subclasses not using the same interface as the parent class.
otherwise some browsers (Firefox, at least) thinks that it needs to
revalidate. At least in my case, it appears that my proxy tacks on
restrictive Cache-Control headers if they aren't there.
1) Don't use $_SERVER, use Input::instance()->server(). This fixes the problem
that when you use a browser that doesn't pass in an Accept-Encoding, we'd
barf on a missing array key
2) Don't bother looking up the _gz key if we don't have gzencode, because we
probably didn't store one.
3) Only emit the gzip Content-Encoding header if we're actually sending back
gzipped data.
1) Create public javascript() and css() functions and turn __call()
into a private function to protect us against having some random
type show up in there. Otherwise anything you put in the 2nd
argument gets emitted in the header which is a security hole.
2) Fix a bug ("$key = $key[0]") which was breaking functionality.
Eliminate the hex check, it's not really necessary in the majority
case and doesn't hurt us in edge cases.
3) Convert some empty() calls to !, no need for a function call there.
4) Add phpDoc.
1) CSS files are added to the combined version by use of $theme->css() or $theme->css_theme() methods
2) url references in the css are converted to full paths as opposed to relative
3) @import statements in the css are resolved as well.
4) need to move the [if IE] statements into the css files so the will be honored in the browser. currently the ie fix css are always included.
