During the various rebases a \n got lost :(

Like requested in https://github.com/arduino/Arduino/issues/5455

Update CustomCharacter.ino

Added lcd.setCursor(0,0); in CustomCharacter.ino example for LCD, it didn't work without it for me. Also removed unnecessary space.

fix compatibility with Galileo and Edison

Due to website configuration changes, every url starting with http://arduino.cc has been changed to http://www.arduino.cc. Fixes #3191

Previous commit broke the actual functionality. The code was confusing and worked until the previous commit.
The changes make it logically and functionally correct.

In my case I had to change it to make my 16x4 LCD work properly

Fixes #1333

Changedfrom (thisRow, thisCol) to lcd.Setcursor(thisCol, thisRow). It was an error.

Fix of a bug #2199

Adding power connections, just to be thorough

Previously, the row offsets were hardcoded to the ones used for 20x4
displays (which woudl also work for all 2-line displays). Now, the
number of columns given is used to calculate the offsets most likely to
apply.

For 2-line displays and 20x4 displays, the (used) offsets are completel
unchanged. With this change, common 16x4 displays and (if they even
exist) other 4-line and 3-line displays might also work (depending on
the hardware configuration used, of course).

See this page for some info on common LCD sizes and configurations
encountered in practice:

Before, the row value was maximized against _numlines already, but the
value from _numlines is not limited anywhere, so it could be longer than
the length of _row_offsets. This check makes sure the array bounds is
never exceeded.
