Rename binary: shellfu-get to sfpath

The only purpose of the binary is to show local Shellfu path and it's
in every single Shellfu script.  Let's save people some typing.

README.md

 
 After installing, one of the first things you can do is:
 
-    shellfu-get path
-    shellfu-get --version
+    sfpath
+    sfpath --version
 
 That should return path to *shellfu.sh* and version, respectively.
 And that's also *all* this command does.
 
     #!/usr/bin/bash
 
-    . "$(shellfu-get path)" || exit 3
+    . "$(sfpath)" || exit 3
 
     shellfu import pretty
 
 
 This is how above script works:
 
- 1. shellfu-get provides path to the main shellfu.sh, which defines
+ 1. sfpath provides path to the main shellfu.sh, which defines
     `shellfu()` function (plus a bunch of boring variables).
 
  2. Using `shellfu import pretty`, we're importing module called "pretty".
