Fix load_some() installation to handle file paths instead of names.

The ls command in for loop has a pattern now, so full paths are
returned. The user prompt and symbolic link have been updated to handle
this.

Also, not all plugins have '.plugin.' in the middle of their names and
weren't showing up on user prompt. With this commit, everything after
the first period in the file name is stripped.
