Replace UTF-8 0xa0 with space 0x20

[martinmoene]

Some of the 0xa0 space characters in the .md files render as 'nothing' in the HTML and the PDF output.

See for example "Isat" and "aperson" in How to start:

How to start?

Whenever Isat down with aperson

It appears for the first time in the PDF of 2015-09-03.

I suspect these characters can safely be replaced with normal space characters (when there are no outstanding PRs for these files...).

Files with 0xa0:

020_Part1Marker.md
030_Motivations.md
040_Three_Essential_Tools.md
050_Its_Not_a_Test.md
060_Statement_First_Programming.md
070_Practicing_What_We_Already_Learned.md
080_Sorting_out_the_bits.md
090_How_to_start.md
100_Analysis_In_TDD.md
110_Constrained_Non_Determinism.md
120_What_is_the_scope_of_a_Statement_in_TDD.md
130_Boundaries.md
140_Triangulation.md
150_Part2Marker.md
160_Composable_Design.md

Other files have Windows-1252 encoding (didn't check all files).

Hmm... that makes me wonder... I didn't change most of those files around September. I'm curious what made the changes. One thing I remember is that around that time, I started using Visual Studio Code editor for writing.

I'll see if I can make a small script that will monitor for such things as broken encoding and strange characters appearing. It might be a good idea to put it on Travis or a similar service to check each commit.
