Use three methods to determine the entry point of the game process.

These are:

	1. Reading from EAX after the process has been created in suspended state (works on Windows, but not on Wine).
	2. EnumProcessModules + name comparison, then parse the PE header (works on Wine, but not on Windows).
	3. Guessing 0x400000, then parse the PE header (works always, unless ASLR is activated).

There might also be the possibility of a brute-force search through all memory pages of the process, but since I haven't encountered a system where neither 1) nor 2) worked with ASLR, I haven't implemented it yet.

Closes #3.
