Make package list use merged recipe definitions

el-get-list-packages wasn't showing descriptions when a partial recipe
in el-get-sources didn't have a :description field.

* el-get-recipes.el
(el-get-read-all-recipes): merge el-get-sources recipes into file
recipes rather than override.
(el-get-recipe-merge): new function.
(el-get-package-def): use it.
