Granulate inspections

[DaGhostman]

As of now, there are a few inspection classes that actually do too much. A good example is the one that performs condition checks, since it:

• Checks for type-unsafe comparison using operators == vs ===
• Checks if in_array has 3rd parameter provided
• Checks for optimizations of conditions if ($var == false) vs if ($var)

And other such inspections, IMO it will benefit greatly if the code is organized in such way that every inspections is in its own class and said class does as less things as possible.

Also I think it will benefit #2 greatly as inspections can be filtered to fit the needs/preferences of many projects/developers as possible
