Issue #184, Issue #186, ++

[dalehenrich]

• Issue need to support button bar ... similar to menu support #186: add button bar client element (radio buttons)
• build new deconstructed class browser with instance/class buttons, protocol list, method list to replace current instance/class method list and funky protocol handling (also Issue need to support button bar ... similar to menu support #186)
• Issue persist open windows with windows restore command to reopen windows on login #184:
  • windows restore command restores, windows from previous session login
  • Window >> history menu item on each window for viewing previous window contents
• text windows honor the #canDiscardEdits message and a #promptFroCancel dialog is brought up - no longer silently losing unsaved changes
• updateClient command (client-side builtIn) uses $GS_HOME/tode/default/pharo/todeLoad.st or $GS_HOME/tode/local/pharo/todeLoad.st to be consistent with the $GS_HOME/bin/createTodeImage and $GS_HOME/bin/updateTodeImage bash scripts
• attempt to allow some level of mismatch between client and server tODE versions - effectiveApiVersion maintained for certain features on client and server
• make sure that the name of a new package file is consistent with the name of the package when parsed
• commit message argument for mc commit command

Upgrade steps
For best results upgrade the client image first. An upgraded client image can be used with a non-upgraded stone, but an upgraded stone may produce walk backs when used with a non-upgraded client image:

1. Quit your todeClient image

2. Use the updateTodeImage script to upgrade the client first:

     $GS_HOME/bin/updateTodeImage

3. Restart your todeClient image:

     $GS_HOME/bin/todeClient

4. Upgrade the server using the following commands in the tODE shell:

     bu backup pre-upgrade.dbf # make a backup before upgrading
     close                                    # this upgrade changes window handling
     project load Tode                 # update Tode project
     bu backup home.dbf            # create new backup
     bu snapshot home.dbf         # create new snapshot
     project list                             # refresh project list

NOTE: if you are using a local clone of the tODE repository do a git pull to refresh your local clone before running the above upgrade steps:

git pull origin dev
