Toaster enhancement set posted

Hi all,

I have been working on a large set of enhancements and fixes, and I have posted the patch here if you would like to take a look (rather than spamming you with a huge email :-).

    http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib?h=dreyna%2Ftoaster%2Fproject_specific_12785

This work was driven by two things:

  (a) The opportunity to use Toaster as the configuration tool for third-party GUIs. Wind River is in the process of open sourcing its Eclipse plug-ins for application and project development. The those plug-ins currently work with Wind River Workbench and Intel System Studio, and we are in the process of open sourcing them to Eclipse.org for all users.

  (b) Comments from the YP Birds-of-a-Feather meeting at ELCE Prague. There were several comments made about limitations with Toaster. Those needs aligned nicely with my personal goals with Toaster and especially the requirements of the above opportunity.

Here is a summary of the included content:

The primary driving enhancement:

*  Bug 12785 - Support Project Specific configuration for external
   tools (e.g. ISS, Eclipse)

  -  Isolated project-specific configuration page (full Toaster context
     hidden)
  -  Support for new project, reconfigure existing project, and import
     existing command line project
  -  Ability to define variables (e.g. image recipe) and pass them back
     to external GUI
  -  Ability to execute the cloning phase, so that external GUI receive
     a buildable project
  -  Ability to call back to the external GUI when updates are completed
     and ready
  -  Compatibility of above projects with the normal full Toaster interface
  -  Ability to pass to a 'complete' or 'cancel' web page so that the
     external GUI can immediately stop that Toaster instance, and not
     leave dangling servers nor edit sessions open

Here are the supporting enhancements, where at least the
back end is implemented:

*  Bug 12821 - Make Toaster conf changes compatible with command line usage
*  Bug 12822 - Support importing user changes to conf files into Toaster
*  Bug 12823 - Support importing user build directories into Toaster
*  Bug 12824 - Scan imported layers for content so that they are
               immediately available
*  Bug 12825 - show layer clone item in progress bar

Here are defects fixed:

*  Bug 12817 - builddelete.py requires explicit 'add_arguments'
*  Bug 12818 - Remove orphaned imported layers when project is deleted
*  Bug 12819 - build using selected bitbake env, not Toaster's env
*  Bug 12820 - Toaster randomizes the layer order in toaster_bblayers.conf
*  Bug 12826 - fix imported layer management
