Fix misleading module description and link type description for "flag_count"

Problem/Motivation

The module description of the "flag_count" module says the following:

Provides an example on how to display flag counts

But this module provides a perfectly fine "Count link" link type which additionally displays the flag count together with the flag itself. The description of this type is:

An example AJAX action link which displays the count with the flag.

Which should be changed as well, because this flag type isn't an example.

Steps to reproduce

Proposed resolution

Fix the strings accordingly.

Remaining tasks

User interface changes

API changes

Data model changes
