Add command line capabilities

Allows sending openrecoveryscript commands to TWRP via shell.
This may be handy for visually impaired users, for various one
click utilities to drive TWRP commands from a computer, for using
TWRP when a catastrophic hardware failure like a shattered screen
prevents you from being able to use touch, or even on devices like
a TV stick where touch and USB mouse input is unavailable.

This patch also includes a few minor changes to openrecoveryscript
including proper support for rebooting via the script and for
decrypting the device via the command line.

TW_SCREEN_BLANK_ON_BOOT will jolt the screen/touch driver.

If on the default settings the screen will only kick in to action
AFTER it has gone to sleep once and has been woken up again with a
key press, this will be needed to set to 'true' in the
BoardConfig.mk

The code was already there, Dees_Troy and I thought it would be
nice to make it a switch to control at compile time.

Support reading since_epoch and secondary brightness files

TWFunc::Fixup_Time_On_Boot: Will now try to read
/sys/class/rtc/rtc0/since_epoch to correct time, if that fails
it will try to use the ats files to correct time.

TWFunc::Set_Brightness: One single function to set brightness
from both the automated functions and the gui actions. It is
able to set a second brightness path if present, it will set
them both the same value. Many Sony devices have 2 brightness
files in the sysfs that must be set to properly set the
brightness.

Allow blacklisting input devices by build flag

Usage:
TW_INPUT_BLACKLIST := accelerometer
TW_INPUT_BLACKLIST := "accelerometer\x0agyroscope"

This can be used to fix touch input on devices where an input
device is breaking touch processing in TWRP.

We are using new line chars to separate multiple devices and in
the make file you specify the new line character with \x0a which
is the hex code in ASCII for a new line.

The new line character might be a bit of a pain to use as a
delimeter, but it is highly unlikely that an OEM will ever name
an input device with a new line character in the name.
