Accordion Menu and Travis script fixes

Fixed bugs:

• Fixed an error where the accordion menu shortcode was calling the incorrect walker class
• Fixed gulp phpcs and travis script so they correctly exclude the 'wpcs' and 'php-codesniffer' directories used only for testing

Mostly Format Changes + Google Analytics

There was only one change to this theme's functionality in this version. I added an additional setting in the Advanced Settings section where users can input their Google Analytics tracking code. The rest of the changes were fixes to the files only used in development and formatting changes according to the Wordpress Coding Standards.

Error Fixes

Modified composer script to remove all development files from release zip and fixed two errors that caused the plugin to fail during installation.

Release of v1.0.0!!

The first release of the TacticalWP theme has finally arrived! Lots of great features added to Foundationpress like shortcodes and support for the version of jQuery that is bundled with the Wordpress core.
