Compilation Speedup (~2.3 seconds) - Reduces compilation overhead by disabling icon-cutter & DMTarget inputs/outputs

[PowerfulBacon]

About The Pull Request

• Removes icon-cutter from the compilation step since we don't actually use it and it introduces A LOT of overhead.
• Changes it so that DM will always compile. GLOBing every single code file in the codebase adds a small amount of overhead.
• Executes DM step before TGUI step, which will probably save a zero amount of time.

People with faster CPUs (and ones with turboboost) will see less improvements than I am seeing since I have quite an old PC.

Why It's Good For The Game

Our compilation time is starting to get a bit ridiculous and there are some easy savings to be had by removing high-overhead systems from the build steps.

Testing Photographs and Procedure

All tests were done with the same programs opened and visual studio focused. (Unfocusing it increases compilation times by ~2x).

Overhead was measured by taking the total build time and subtracting the DM target build time from it.

Baseline

Test-Run	Overhead (/s)
1	2.632
2	2.543
3	2.634

With Icon-Cutter Change Only

Test-Run	Overhead (/s)
1	2.208
2	2.174

~0.4 seconds saved

With DM-Step Change Only

Test-Run	Overhead (/s)
1	1.299
2	1.323
3	1.296

~1.3s saved

After

Test-Run	Overhead (/s)
1	0.337
2	0.352
3	0.344

~2.3s saved

If you do the math there are 0.6s of savings unaccounted for, so I will chalk that down to re-ordering the DMtarget and the TGUI target.

Actually lets be honest, we are never going to actually use icon cutter so I'm just deleting it rather than commenting it out.
