Lately Social Blade server has started to work unreliably for some users, generating "Error reference number: 502" messages instead of producing actual widgets with statistics.

To deal with that, the extension has been updated to check if widgets are getting loaded for real, and not error pages. In the latter case, the extension now repeats the corresponding query after a short pause.

As a result, the time of loading of the full table of (up to) twenty widgets can depend on how well Social Blade currently working. But with this update, it will load at least.

Options page updated to three columns view for channel entries; the code of the extension is a bit cleaned up.
