Feature: The featureless make program now supports the "write" operation.

This is an oversight on my part.
There should be an operation to write to a file.

There are two forms of this new "write" operation.
1) Truncate a file (deletes all data within a file).
2) Append to a file.

A file is created if it does not already exist in both cases.

The "write" operation supports some standard escape sequences as well as some non-standard ones.

Standard Escape Sequences:
- "\f": Form Feed.
- "\n": New Line.
- "\r": Carriage Return.
- "\t": Tab.
- "\v": Vertical Tab.
- "\\": Backslash Character (may require additional slashes in certain circumstances.)
- "\0": NULL Character.

Non-Standard Escape Sequences:
- "\U+": Unicode Sequence (followed by a valid Unicode sequence with a minimum 4 hexidecimal digits and a maximum of 6 hexidecimal digits).
- "\U-": Terminate a Unicode Sequence, allowing for "\U+000A\U-5" to be equivalent to "\n5".
