fix #570 Wrong content type in IE 8 with asyncFormSubmit.

In IE 8, setting the enctype attribute of a form with the

 form.enctype = value;

The following line works better:
 form.setAttribute("enctype", value);
fix #572 Exception when accessing history.state in IE 10

Accessing history.state sometimes raises an exception in IE10,
instead of returning null.
This fix surrounds accesses to history.state with try / catch
blocks.
fix #571 "this.__delegateMapping is null" when unloading a page

cases when unloading a page. This commit fixes this small issue.
fix #573 Style tag reload for html:Template

Calling the getCSSClassNames method of the template context in the initWidget of the html:Template widget was causing a further style tag reload, with a significant performance degradation.

Storing the classnames while writing the markup allows for an optimization of style tags reloads, which is done through the CSSMgr stop/resume mechanism.

fix #550 reorder some tests

Change order of the tests so the long ones do not block the whole campaign
at the end. Speeds up the whole campaign by ~20s (from 2m10s to 1m49 on my
machine) on 8 CPUs.

Related to #538.
refactor Drag tests

1. Removed tolerance which was hiding problems in IE8 and changed the test
environment (increased border size to 15px) to underline the problems in IE8
2. assertTrue etc. -> assertEquals
3. Extracted abstract class to handle shared code
4. Renamed files to follow the unwritten convention that Test means an
executable test, while TestCase - abstract shared class

Close #544.
