Make the script generalize to user

[wanhuz]

As in #13, make Dropout is usable to all user instead of only, well, myself.

• Make moving taskbar works for different setup
• Make user are able to choose which monitor is the monitor the game is streaming
• Create simple script to setup first-time configuration
• Simple load/save config file
• Finalize decision such as how long until it safe to save desktop icon
• And more..

I'd try to make this simpler. Add config file to the apps directory and let user changes what they want the program to do. The explanation to this config file should be written in docs.

Example config:

setdefaultdisplay = 3 enablesteamoverlayhotkey = true enablesteamcontrollerresethotkey = true enableexitgamehotkey = true enabledefaulttaskbar = true enabledefaultdesktopicon = true monitoronlyhavesteamandgame = true enableaudioseperation = true savedesktopiconeverysecs = 10 reopenfolderwhentaskbarchange = false defaultaudio = "Realtek High Definition Audio\Device\Speakers\Render" targetaudio = "VB-Audio Virtual Cable\Device\CABLE Input\Render"

For most part, I'm able to make the configuration option works, except for two:

1. Taskbar - Make an context menu to save taskbar registry key. However, user need to set their desired taskbar on their desired display one time.
2. Default Monitor - Current script only uses 2 coordinate to detect whether an apps is running on the monitor if the monitor are arranged from left to right. This will not work if monitor are from right to left or up or down. Etc. This needs major rewrite and testing.

EDIT: For 2, thankfully, critical function "NumAppAt" is only used at Dropout.ahk. So, the function only need to change a bit to support 4 coordinate detection.
