Change most used to most directly depended upon

[zzmp]

Fixes #110

This is very verbose (it calls it Most Directly Depended Upon).
This calls the field Most Depended Upon, but is still verbose with the data field, calling the property most_directly_depended_upon.
Is this what we want?

@alexcrichton you mentioned in the issue to sort by dependencies-on.
Is this sufficient to count only direct dependencies?

[reem]

I'd rather "Most Depended Upon"

[zzmp]

@reem Updated the HTML to call it "Most Depended Upon" but leave the data as most_directly_depended_upon for verbosity.

I can't see this column defined in the "schema" (as in, it's not mentioned in the migration code), am I missing something?

(If it turns out this isn't defined, one may wish to look at reverse_dependencies which does essentially exactly the same thing.)

[alexcrichton]

Yes unfortunately as @huonw mentioned this will require some deeper changes to implement. We do not currently track the number of immediate dependencies in the row for each crate. Additionally, the reverse dependencies page is currently implemented by joining many tables together, but for a home-page, often used query I don't think this is gonna cut it.

To implement this a counter will need to be maintained on the crates table of all immediate dependencies, both when dependencies are added as well as removed. That way we can actually just use a ORDER BY clause to sort everything correctly.

Closing because very old.
