Fixes aFarkas#43

Well, sort of. Moves the changelog into the repo so hopefully it will
be easier to update (remember to update?) going forward. It does *not*
bring the changelog up-to-date with the current version, though.

+#### **As of April 18th, 2011**, [html5shim](http://code.google.com/p/html5shim/), [html5shiv](http://code.google.com/p/html5shiv/), [modernizr](https://github.com/Modernizr/Modernizr) all have been updated to use iepp v2.
+
+## v2 changelog
+
+here is the list of fixed issues and made changes. I have also added a list of known issues (The first one is really critical, but needs a lot work...).
+
+### Fixes:
+
+* print error on second print/print preview
+* allow styling through body id (i.e.: `body#some-id article`)
+* wrong selector parsing in IE8 (subbug: `@media print { }` blocks in `media=all` stylesheets are ignored, but fixed a lot more than just that)
+* alternate/disabled stylesheets aren't parsed (can solve problems with mediaqueries polyfills/styleswitchers)
+* styles with multiple media declaration or mediaqueries (i.e.:` media="screen, projection"`, `media="only screen..."`) are not used as print styles (unless, they have print or all medium) (this also fixes a lot of slowness and crashes)
+* reset default media type to `"all"`, with every new stylesheet (fixes errors, if a stylesheet had no media attribute, but the previous  had a non-print media-attribute)
+
+### Features:
+
+#### Configuration:
+
+* iepp.html5elements:  override shimed html5elements (developer can add additional html5elements or reduce the elements)
+* iepp.disablePP: disables print protection without disabling standard shiv (in case, print protection causes too much trouble, it's still a big hack)
+
+#### Extras:
+* simple testsuite 
+* [unofficial] API (created for testing, but can be used for monkey patching)
+
+
+### Known issues:
+
+* `@media screen {}` blocks in media all are treated as print-styles (This would need a big rewrite)
+* selector order (Currently, this seems "by design", but should be changed. Also needs a big rewrite)
+* change of selector specificity (`.iepp_article <-> article`) (Currently this seems "by design", but for IE7 and IE8, it can be changed to` [data-iepp-elem="article"] `<-> `article`)
+
+Before someone is looking into the first two known issues, we should create good performance tests. Fixing last issue only makes sense, if we also fix the selector order...
+
