[ArcDPS] Update Script

This script is a bit old, but I've updated it with the extras dll the other day at https://gist.github.com/OneFaced/764f9c5c7bef1c49a31d928c223bcb24. What this script does is make sure you have the latest version of ArcDPS prior to running GuildWars 2. This is a few step process when you run the script.

1. Script checks the md5sum arc provides for the primary ArcDPS dll
2. If the dll checksum on your install doesn't match, it downloads the ArcDPS dll as well as buildtemplates and extra dlls.
3. It then starts GuildWars 2 for you.

If the md5sum does match what is on disk, no further files are downloaded and GuildWars 2 is started for you.

To get started, go to the script at https://gist.github.com/OneFaced/764f9c5c7bef1c49a31d928c223bcb24. Click on "Download Zip" in the upper right and open the zip file. It will contain a folder and within the folder is UpdateArcDps.cmd. Place this file on your desktop or wherever you want to run GuildWars 2 from. The script points to the default location of where GuildWars 2 is installed to. Adjust as necessary on line 25.

If you decide you want to pass command line arguments to GuildWars, such as -maploadinfo, add those as an argument on line 18. Examples are provided on line 15.

And that's about it. Always use the script instead of running GuildWars 2 directly to make sure your ArcDPS is up to date with the latest version.
