- 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.

Added a new requirement ( pip install request ) and some logic to get it working, I won't blame you if you reject this PR but this is what made it work on my machine

Added an Exception handling to the offending urlretrieve() call for the issue #108 https://github.com/espressif/arduino-esp32/issues/108

It's not really a fix but the failure message is much more elegant than the initial stack trace as it hints at the solution to the setup problem rather than confusing the user into Windows problems.

adds autoreset after firmware upload
