Add a new Assembly Option to show "li" instead of "move" where possible in the Assembly window or tab

[ghost]

Many veteran MIPS assembly programmers are used to see li mnemonic, that is "load immediate", in MIPS assembly files, viewers and editors and not move mnemonic.

The move mnemonic in MIPS is used only when the source is a register but if the source is an immediate then the li mnemonic is used instead.

For example if the new option is disabled then the PCSX-Redux user may see in the Assembly window or tab something like this:

move $v0, 0x1234

But if the PCSX-Redux user enables the new option then he or she will see the same instruction as
li $v0, 0x1234 instead (the word "move" just changed to "li").

This new Assembly Option can be useful for veteran MIPS programmers but new PCSX-Redux users that never programmed in MIPS but more in x86 or x64 assembly may want to disable this new option because move $a0, 0x1234 is more similar to mov eax, 1234h than li $a0, 0x1234.
