Folder/symlink name should be the one from galaxy

[franklinkim]

when I install a role from galaxy i.e.

$ arm install neel.apt

it will install it like this

/.installed_roles
  /New-Edge-Engineering.ansible-apt
...
/roles
  /New-Edge-Engineering.ansible-apt

but I think it should be like the ansible-galaxy command:

/.installed_roles
  /neel.apt
...
/roles
   /neel.apt

I know you can use the alias but it seems not to work with a dot in the name and it only affects the symlink...
