common: remove {Left, Right}PadString (#168)
Fixes #134 Those functions are unused in the whole Tendermint Github organization plus they were unnecessariy verbose and could have been concisely replaced with ```go func RightPadString(s string, totalLength uint) string { return fmt.Sprintf("% *s", totalLength, s) } func LeftPadString(s string, totalLength uint) string { return fmt.Sprintf("% -*s", totalLength, s) } ``` delete them anyways
