Update/Correct LiquidCrystal Tutorial Page #1116

Currently the LiquidCrystal tutorial is missing one critical piece of 
information that causes
newbies to end up with a non working LCD. While it is simple and may be obvious 
to most, to many it is not obvious. The missing information is that the 
connections to the LCD module must be soldered.

If you look at the tutorial page:
Nowhere on it does it ever mention needing to solder the connections to the LCD 
module.
It shows them soldered in the photo, but it never says it in the 
text/instructions.
In fact it doesn't even list solder in the h/w requirements.
Ignoring the obvious typo of "LED" vs "LCD" this is really the only 
instructions:

"To wire your LED screen to your Arduino, connect the following pins"

And then a fritzing diagram below.

So the issue is that users can follow the tutorial to the letter and have 
everything
"wired" correctly and end up with a non working LCD because the tutorial fails
to mention the requirement of soldering the connections to the LCD.

Also, when updating the tutorial, change the typo of LED that should be LCD.
