White-space clean up

[UnitedMarsupials-zz]

This commit makes the following changes:

• Removes blanks, tabs, Ctrl-Ms from ends of lines
• Removes blank lines from beginnings and ends of files
• Replaces sequences of 2 blank lines with 1 blank line
• Replaces sequences of more than 2 blank lines with 2
• Adds line-ending, where it was missing

There are no other changes and output of:

git diff --ignore-blank-lines -w

is empty as expected.

Alternatively, here is the Tcl-script used to perform the clean up: blank-clean.tcl. Run it as something like:

find . -type f \( -name \*.java -o -name \*.cpp -o -name \*.h -o -name \*.hpp \) | \
    xargs tclsh blank-clean.tcl
