Yes, any tag or branch can be selected with `bro-pkg install —version <version or branch>`.

When selecting a version, `bro-pkg update` only considers newer x.y.z release tags for that package.  When selecting a branch, it tracks updates along that branch.

I’ll make —aggregate flag operate on all sources then add an optional "—source <source>” flag for those that just want to operate on a single one.

`bro-pkg refresh` without any flags is currently like a `git pull` from the remote source and what most users will be doing.  Likely only the operators of sources will want to —aggregate (if the package ecosystem becomes large, this operation could take a while to complete).

Yes, newer data from the remote source overwrites local changes.

Sounds good, I’ll have it do that.
