Update/Correct LiquidCrystal Tutorial Page #1149

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.

Actually just noticed that this update will need to be done on several pages as there seems to be page
for each example:

Blink: control of the block-style cursor.
Cursor: control of the underscore-style cursor.
Display: quickly blank the display without losing what's on it.
TextDirection: control which way text flows from the cursor.
Scroll: scroll text left and right.
Serial input: accepts serial input, displays it.
SetCursor: set the cursor position.
Autoscroll: shift text right and left.
