ChestStealer Rusherhack compat

[rfresh2]

Describe the pull
Rusherhack compatibility...kind of...

Without this, rusherhack will completely break lambda's cheststealer module.
This change improves that compatibility but does not fix all issues.

I suspect Rusherhack has some GuiContainer child implementation that causes weird issues with buttons added.

States with both clients present:

• Only Lambda cheststealer on

  • Steal button is textured and placed where rusherhack's steal is - not ideal, but it uses lambda's steal function. Normal Lambda Store button present and works.

• Only Rusherhack cheststealer on

  • rusherhack works as normal, both buttons present and work.

• Both rusherhack and lambda cheststealer on

  • rusherhack buttons both use rusherhack functions. Lambda store button works and uses lambda store function. lambda steal button is not present - not ideal.

Describe how this pull is helpful
Rusherhack is a very popular client. If Rusherhack is not present, this module still works exactly as before.
