ENH: Add encoding option to numpy text IO.

This modifies loadtxt and genfromtxt in several ways intended to add
unicode support for text files by adding an `encoding` keyword to
np.load, np.genfromtxt, np.savetxt, and np.fromregex. The original
treatment of the relevant files was to open them as byte
files, whereas they are now opened as text files with an encoding. When
read, they are decoded to unicode strings for Python3 compatibility,
and when written, they are encoded as specified. For backward
compatibility, the default encoding in both cases is latin1.
