Aion 4.0 No-IP and Windows 10 mouse fix.

This is a patch for Aion to remove the IP restriction and fix various bugs to help keep the game playable.

New features for 1.6.2:

• Fix delay problem when using alt+tab.

New features for 1.6.1:

• For Aion 3.9, updated -fix-39-weapon-switch to allow switching weapons from the skillbar.

New features for 1.6:

• Made some changes to the windowed mouse fix to prevent the cursor from getting stuck.
• The -unlimited-gfx option should work for windowed mode now.
• Added -fix-39-weapon-switch to fix the weapon switching bug in Aion 3.9 which prevents switching weapons while being attacked. The changed code matches Aion 4.0 which doesn't have the bug.

New features for 1.5:

• New windowed mouse fix implementation using rawinput.
• The windowed mouse fix also fixes the problem of the mouse cursor sometimes jumping out of the game window. Use the new -windowed-mouse-fix argument to enable only the windowed fix which should work on all operating systems. This argument can be combined with -win10-mouse-fix or -win10-mouse-fix-autodetect. Note, -win10-mouse-fix always enables the new windowed fix, and -win10-mouse-fix-autodetect enables the windowed fix only if it detects the Windows 10 mouse bug.
• Tested on 4.0 only.

New features for 1.4:

• The IP fix now supports Aion 5.8.
• Added -disable-xigncode command line option to prevent xigncode from loading. Only tested in 5.8.

New features for 1.3:

• Fix a bug for the windowed mode mouse fix that could make it stop working after moving the window.

New features for 1.2:

• The Windows 10 mouse fix now works for windowed mode.
• Added the option -win10-mouse-fix-autodetect which will automatically enable the mouse fix depending on the OS version.

New features for 1.1:

• Added option to enable all graphics options sliders (shadows, water quality, etc) which are otherwise disabled at high resolutions. This feature is enabled by passing the -unlimited-gfx command line argument to aion.bin.

Features:

• Allows the game client to connect to the game server IP specified by the -ip:x.x.x.x command line parameter. (Prevents the error message "No game server is available to the authorization server (6)".)
• Fixes the mouse issue on Windows 10 without needing to run a separate program. This feature is enabled by passing the -win10-mouse-fix command line argument to aion.bin.
• The IP fix can be disabled with -disable-ip-fix in case you only want to use the mouse fix.

Latest binaries: https://github.com/zzsort/Aion-Version-Dll/blob/master/release/AionVersionDll_bin_1.6.2.zip

Extract both version.dll files from the .zip file to the respective bin32 or bin64 folder under the Aion client root. Aion will automatically load version.dll when it launches.

Note: Existing patch dlls should be removed from the bin32/bin64 directories as they may have conflicting functionality.

• Remove: dbghelp.dll
• Remove: d3d8thk.dll
• Remove: d3dx9_38.dll

Mainly tested with the Aion 4.0.0.12 game client on Windows 7 and Windows 10.
