toaster: remove startup questions

This removes the startup questions from toaster and uses the following dir structure.

cwd/toaster.sqlite
cwd/_toaster_clones
cwd/build

You can override TOASTER_CONF to point at the toasterconf.json in meta.

There are still a fair number of directory assumptions that need to be worked out for 2.1 but this should let us start up easier and automate tests better.

Since we are putting the builddir here, we should really allow users to set the SSTATE_DIR and DL_DIR variables. I will try to add that as part of the change needed for 7880 since it has to set a number of new variables.

The following changes since commit 2bd6d137555b44c374853068767e7f4c736898d1:

toaster: Hide "Download build log" button if log doesn't exist (2015-10-07 13:02:07 +0300)
