Setting constant `SSP_CPT_PODCAST` to a post name other than `podcast` causes plugin settings page to disappear

[UmeshSingla]

Describe the bug On setting SSP_CPT_PODCAST to a value different from 'podcast' causes Settings, Options, Extensions page to disappear because the menu page links are hardcoded to use post_type=podcast and do not consider SSP_CPT_PODCAST value.

To Reproduce Steps to reproduce the behavior:

1. Go to wp-config.php, add define('SSP_CPT_PODCAST', 'hello_podcast');
2. Go to wp-admin/plugins.php
3. Scroll down to Seriously Simple Podcasting, and click on settings link.
4. See error - "Sorry you can't access this page"

Expected behavior Settings page should load properly
