update get.py and add get.exe

- get.exe is clickable and will soon download binary form of esptool,
which will really simplify installation on Windows
- get.py does not require any extra modules on Linux and Mac
- ```pip install requests``` required only on Windows (if not using
get.exe)
- Paths are made relative to the file in order to make the windows
executable clickable.
