Add commit msg hook

[roygrssmn]

I have used this project as a base for my script.
I have added a commit-msg that is using the aspell dictionary and same logic as in the original pre-commit script.

Also in this MR:

• bash warnings fix
• update readme
• fix to work on aspell on linux, using the "./" reference
• change from SIGNALS to EXIT

Yikes, I totally forgot about this PR, sorry!

@roygrssmn What's the point of a second file that is mostly identical to pre-commit but has a different name? You could probably just check the name of the file when its executed to determine which actions to take (if any differ between pre-commit and commit-msg).

Thanks for the contribution!

Hey @mprpic, you mean that .commit-msg call .pre-commit script?

I'm saying if you'd like to use that script as a commit-msg hook as well you could instead just modify the instructions to create a symlink from pre-commit to commit-msg instead of duplicating the entire file with just a different name.

Yeah... It'll also mean maintaining 2 different files that do mostly the same thing
