Update pbi-manager10

* Allow using "short-names" for pbi_info / pbi_delete / pbi_update, this
  lets us do something like "pbi_info nginx" and it'll match the first nginx
  it finds

* Add PBI_LICENSE / PBI_TAGS / PBI_SHORTDESC / PBI_DESC as optional
  variables we can set in pbi.conf. LIC / DESC / SHORTDESC will be pulled
  from a port automatically

* When we create a PBI using a module / confdir, we will include the confdir
  in the PBI directory under /usr/pbi/<pbidir>/pbiconf. This will allow
  easy re-creation of a PBI from the port/packages
