Bump version to 1.0.0

It now only ever returns the the number of times the stub has been
called. To assert if it has been called exactly X number of times, use
`stub_called_exact_times` instead.

 # stub.sh [![Build Status](https://travis-ci.org/jimeh/stub.sh.png)](https://travis-ci.org/jimeh/stub.sh)
 
-A set of stubbing helpers for use in bash script tests. Supports stubbing and
+Helpers for bash script testing to stub/fake binaries and functions. Includes
-restoring both binaries and bash functions.
+support for validating number of stub calls, and/or if stub has been called
+with specific arguments.
 
 Particularly useful when used in combination with the simple and elegant
 [assert.sh](https://github.com/lehmannro/assert.sh) test framework.
