Added method to allow checking the source code once IonCube has run for
any un-encoded/encrypted files.
This checks against an array of file extens (used mainly to exclude
images and javascript etc.)
It also checks against an array of paths/filenames.
These 2 should maybe be combined into a single array?
If any files are found to not be encoded and havnt been excluded, then
user is prompted to confirm they wish to proced.
This is designed as a last confirmation that you have encoded all the
files that you need, and are not about to push unsecured files to a
server.
