fixed WEB-8096 Breakpoint is ignored in ExtJS app — But is very slow now (due to >100 scripts) So, I will continue working on it
WEB-4429 Add ability to debug the GWT 2.5.0 super dev mode inside IDEA — real reason of this commit. We set breakpoint by url, but GWT reports sourceUrl in case of redirected script, so... oh, ma!
init WEB-6659 JS Debugger stops at arbitrary point in code — well, set by url is not reliable way due to Chrome bugs Now we set breakpoint by script id. This way is slow, but solves our problems
init WEB-6413 sourcemap backed breakpoints do not work until page is loaded — we pause script on first line now, so, we can check sourcemap too.
