Using PR #35 fork as it contains a fix for dll-syringe building. Compiling with nightly.

warning: the following packages contain code that will be rejected by a future version of Rust: dll-syringe v0.15.2 (https://github.com/fry/dll-syringe?rev=0a8b18e#0a8b18ef)
note:
To solve this problem, you can try the following approaches:

• If the issue is not solved by updating the dependencies, a fix has to be
  implemented by those dependencies. You can help with that by notifying the
  maintainers of this problem (e.g. by creating a bug report) or by proposing a
  fix to the maintainers (e.g. by creating a pull request):

  • dll-syringe@0.15.2
  • Repository: https://github.com/OpenByteDev/dll-syringe
  • Detailed warning command: cargo report future-incompatibilities --id 1 --package dll-syringe@0.15.2

• If waiting for an upstream fix is not an option, you can use the [patch]
  section in Cargo.toml to use your own version of the dependency. For more
  information, see:
  https://doc.rust-lang.org/cargo/reference/overriding-dependencies.html#the-patch-section

note: this report can be shown with cargo report future-incompatibilities --id 1
The following warnings were discovered during the build. These warnings are an
indication that the packages contain code that will become an error in a
future release of Rust. These warnings typically cover changes to close
soundness problems, unintended or undocumented behavior, or critical problems
that cannot be fixed in a backwards-compatible fashion, and are not expected
to be in wide use.

Each warning should contain a link for more information on what the warning
means and how to resolve it.

Threw this together quickly, I'll soon create a fork with it implemented for people to use - if there are any issues with this please write do tell or PR a fix :3

I have implemented this into my fork,
if you would like to use this fork, the cargo dep would look as follows;
dll-syringe = { git = "https://github.com/ElonGaties/dll-syringe", branch = "master" }
