bitbake: toaster: release name consistency

Small changes to the project, new project and all layers
pages to ensure consitency in release naming across the
interface.

The changes are:

* In the new project page, change the label 'release version' to
'release'

* In the new project page, sort the releases in the dropdown menu
in ascending alphabetical order

* In the new project page, remove the release name that was
showing between brackets after the release description in the
dropdown menu

* In the project page, make sure the release information
shows the release description field instead of the release name,
to keep consistency with the new project page

* In the all layers page, provide some help text for the branch 'HEAD'
