Adds a test for vip_init.php file inclusion
As it was reported, there might be some false positive errors about checking a requirement of vip_init.php from functions.php. This test should make sure that this is no longer true
Tries to make ->get_path() working from the test case WiP
replaces start of a string by word boundary in requre_once regex pattern
Not necessarily related to the original false-positive issue, but it's possible that there's gonna be a empty space or even a tab on the beginning of a line and thus the regex fails.
Adds a test validiting vip-init check
This commit initializes theme scanner and points it to a data directory inside tests checking for vip-init only
Creates a test theme in a tests/data directory
This theme can be used in scanner tests and is actually being used in VIPInitCheck test - it's update is a part of this commit
improves vip init regex
The regex now checks for whole path to vip-init.php file (including WP_CONTENT_DIR) for consistency / readability.
Merge pull request #169 from david-binda/falsepositive

Updates regex for checking if vip-init is present and adds test-theme to test/data
