Initial commit
Adds Fish prompt to repo

This commit adds a default Fish prompt that incorporates the latest exit
code (via a color coded lightning bolt) on the left, and the current Git
branch, dirty status (via a color coded circle), and the current working
directory on the right.
Adds `ls` function for most common options

This commit adds the `ls` function. This function automatically passes
the -l option for listing the files, -A for including normally hidden
files (dot files), -G for adding colors, and -F for showing the
differences between symbolic links, executables, etc.
fix_ascii for changing line endings and ASCII bugs

This commit includes the fix_ascii function. This function zips a
directory, then unzips it. This achieves the following goals:

- Change all line endings to (Unix) LF
- Avoids mangling binary files (images, etc.)
Merge branch 'release/v1.0'

This represents version 1.0 of the @ciarand-fish-functions repo.
