build tool: new feature

Hi all,

with DEV300 m61, the build tool got a new feature - ability to manage 
build process via generated html page. The you can activate this feature 
with "--interactive" switch and rebuild/delete modules with right 
mouse-click. The build process (for example "build --all") will be not 
stopped...
This feature so far is a kind of "pilot", so it's not complete, I'm 
waiting for feedback.
Hope, you enjoy it.
Best regards,

Vladimir

PS: by the way, the job-management in multiprocessing modus has been 
reworked, now the tool loads build machine more optimally.
