The third version

New things;

• Now includes a similar mode to the --firstrun option in GloriousEggroll's scripts. (Thanks @GloriousEggroll for the help in that)
• Now renames itself between launching Warframe to ensure that the game doesn't override it.
• Now only downloads cache files once, letting the built-in incremental patcher in Warframe keep them updated.

NB: The libcurl dll is still unchanged, but added to this release as well to simplify for first installs.

Second build

This version adds support for choosing the Warframe executable to launch, as well as help text and some code restructuring.
You can also now run a cache optimization pass without downloading any updates.

(The libcurl DLL is unchanged from the original release)

First push

A first "working" version of the proton launcher, will update and launch Warframe for you.

Only bare support for command line options at the moment and no configuration possibilities.

The files provided will download and run a full Warframe install into the .. folder, as it's designed to live in /Warframe/Tools/Launcher.exe
