Error and misspelling in README

[melgu]

Inside the README under section Extension Settings, it says:

arduino.libraryPath: Sprcifies the serial port borad are connected (Note: Absolute path only).

Correct would be:

arduino.libraryPath: Specifies the path to your library directory. Default is path /Documents/Arduino/libraries (Absolute path only).

You should also correct this inside the Settings ("Default is path" instead of "Default is used path to").

Also, at arduino.serialPort you misspelled board (right now it says borad).
