Address MD5 hashing algorithm

[TheLimeGlass]

Suggestion

MD5 hashing algorithm in ExprHash is marked as deprecated and provides a warning in the description.

We need to either deprecate it at parsing level or outright remove MD5 capabilities in 2.8.

Potentially replace with another strong algorithm?

Why?

MD5 has been cracked, and is not secure anymore.
