Fix BUNDLE_PATH and horrible lag when using themes with Image BGs

[acquitelol]

• Uses the BUNDLE_PATH constant instead of the ENMITY_PATH constant which fixes the tweak not building through the Action.
• Add a different Package Identifier to the Rootless Dev tweak as I forgot to do that beforehand
• Fix the extreme lag when having a theme with an Image BG.

Original:

UIView *subview = self.subviews[[self.subviews count] >= 3 ? [self.subviews count] - 3 : 0];

New:

int count = [self.subviews count];
UIView *subview = self.subviews[(count >= 3 && count <= 5) ? 2 : 0];
