The collapsible sidebar adds a new JavaScript dependency and behavior to
Latest mode only. There are a number of ways of to make the deviation
but we think now is the time to start splitting by module.
This patch adds a new ResourceLoader module, skins.vector.legacy.js, and
moves the existing JavaScript into it. The old module, skins.vector.js,
has been given a currently matching index.js entry point that references
the collapsible tabs' files by reaching across directories. It's not
quite ideal as usually ResourceLoader modules and directory structures
strive for 1:1 correspondence but this patch makes the bold assertions
that it's better than a file copy, better than a new
"skins.vector.common.js" ResourceLoader module, more compatible than a
symlink, and the existing jQuery tabs implementation will eventually be
replaced in Latest mode.
A "Legacy" module was added instead of a "Latest" with the assumption
that active development should generally be considered "latest" and
Legacy an intentional distinction.
