Added rule to prevent trivial patching as a solution

[3rdit]

Adds rule to detail that patching only is not a solution. Closes #133

I do not think you did the best job to explain it. It is more like that the crackme should not allow patching as a solution unless patching is the theme, and it is not trivial. Users can still make e.g., a keygen that can be patched trivially, but the challenge description should not allow a patching to be considered a valid solution

The motivation for this change is that sometimes the challenge author allows a trivial patching when it should not, and another user would submit a patching solution. When we reject it citing patching, the user might be confused and/or feel mistreated. So we should not allow patching to be allowed in the beginning
