2. Attempt to start Blockly Editor

Error msg in Chrome.

Version (SVN revision) of

How about checking the default browser first, then message that Chrome may fail 
and suggest (or start) a link to Firefox?

Just tested:
* FireFox - no problems;
* Chrome - error message, no connectin to IDE, can be used for assembling code;
* IE - no connection to IDE, some problems with code assembling, weird cursor 
location shift;

I suggest leaving only FF as supported browser, if no FF found, warn user, that 
other browsers are not supported and leave a choice to cancel action or open in 
default browser.
