event/hob: Add a button for network tests in the proxy settings

This patch allows the user to check the network connectivity in
the "Proxy" page ("Settings" dialog) by adding a button which provides
this functionality. It also disables retrigerring sanity checks if the
proxy values are changed, since now the proxy checks are explicit.
Note that this patch depends on a patch in oe-core
("sanity.bbclass: trigger network tests explicitly"). It will
not work properly if the patch in oe-core is not merged.

hob: image size displayed wrong size in edit packages screen

    size_str = '%.1f' % (size*1.0/(1024*1024)) + ' MB'
    from /bitbake/lib/bb/ui/crumbs/hobpages.py file transformed
    the size in MB. In our file it was again multiplied by 1024
    instead of doing a division by 1024, which brought a faulty size on
    the edit packages screen.
