generate html from plist

[gyorb]

A script should be created
createHTMLReport -r report_dir -o report.html //generate a report.html for all plist in the directory
createHTMLReport -p plist.plist -o report.html //generate report to a single plist

reports.html would contain
-all the errors in the report directory
-source code to which the bug path points to
-navigable bug steps.

CodeChecker parse command should support the new html output.
