bitbake: hob/bitbake: create a template (a .bb file) from hob through bitbake

Modified generateNewImage function from cooker, in order to be used to
save a template in Hob.
Created a command to ensure that some dirs are created. The templates
(recipes) will be saved in {TOPDIR}/recipes/images folder.
Called these methods from Hob.
