Updated T6 AC GSC (#214)

* PlutoT6 AC GSC Updated

PlutoT6's GSC modding capabilities changed, this allows us to bring the script on parity with the IW4x one. The following things changed:
*  Script no longer replaces stock GSC since custom GSC files are now supported.
* The Script now captures the last time the client used his attack button; this is used to detect trigger bots.
* Cleaned up the code a bit

* Create README.MD

Basic installation guide.

+# T6
+
+This brings IW4M-Admins's Anti-cheat to Plutonium T6
+The following limitations are known:
+* Can't get the recoil from weapons fire; you have to disable this detection type manually.
+* in extreme cases it can produce false positives for Snap and Offset detection.
+
+## Installation
+
+
+Move `_customcallbacks.gsc` to `%localappdata%\Plutonium\storage\t6\scripts\mp\`
+
+Add this to the WeaponNameParserConfigurations List in the StatsPluginSettings.json file:
+
+```
+    {
+      "Game": "T6",
+      "Delimiters": [
+        "_",
+        "+"
+      ],
+      "WeaponSuffix": "mp",
+      "WeaponPrefix": null
+    }
+```
+
+Now create the following entry for __EVERY__ T6 server you are using this on in the ServerDetectionTypes list:
+
+```
+    "1270014976": [
+        "Offset",
+        "Strain",
+        "Snap"
+      ]
+```
