Merge branch 'release-2.140.110'

    powerup does not try to do any chmods now.
    i have seen a failure of powerup due to chmods composer tries to do during the install step; this can be fixed by running standup again.  subsequent powerups should work fine.
    added a switchto function to jump to an application directory.  e.g. switchto ecocor6 will jump into the apps/ecocor6/avenger5 directory.
    stopped adding the swap disk automatically in revamp.  having a ram disk on an SSD based machine can use up the lifespan too quickly, so it was though better to not add it unless explicitly asked.
    if the variable ADD_SWAP is set (to anything), then the swap drive will be added.  otherwise it will not be.  usage could be like:
    export ADD_SWAP=true ; revamp_cakelampvm
    added "map archive = no" to global section in samba config to stop archive bit mapping feature from hosing executable bits.
    locked the revamp command to only operate on a host that contains "cakelampvm" to avoid scorching other hosts.
