[PATCH 1/2] ui/crumbs/utils.py: new file for choosing terminals

[Saul Wold <sgw@linux.intel.com>]

Adding this simple version of a terminal selector for use
hob since it's needed. Moving forward in the 1.3 release
the existing code in meta/lib/oe/termnial.py will be migrated
to core bitbake code and this will use that code.
