This patch adds create and import keypair actions into
Angularized key pair panel as global action.
Also, to load public key from file, this patch uses
load-edit directive.
To use load-edit directive from angular-schema-form,
i.e. from separated scope, this patch enables to configure
callback function to get content of textarea in load-edit.
