Add 'force security' to display OLS and FLS for a given SObject, organized by Profile

The new command allows to display the OLS and FLS for a given SObject (standard object or custom object) by Profile. To make it more readable, it groups the Profiles that have the exact same OLS and FLS together, making the table smaller.

Because of the complexity of the output, I've decided to write it as a HTML that is displayed inside the browser.

A future version will add the ability to copy the OLS+FLS "footprint" from one set of profile to another.

P.S: I have no idea why Github is finding differences in tabulation between the two versions of main.go (I just added cmdSecurity)
