We have our master branch that we merge our features into. I need to be able to increment our version on commit/merge to the master automatically as a part of the merge. Is there a way i can do this so that the upped version is committed as a part of this commit without having to have an automatic 're checkout, change, commit' that will effectively double all our commits?

You can use git hooks for that.
The pre-commit hook specifically. You can create one from the sample in .git/hooks/pre-commit.sample by removing the .sample suffix and editing it. The content of pre-commit will be executed just before the commit.
It could contain something like this
#!/bin/sh
command-that-increases-version version.text
git add version.text
Any modification of version.text will then be included in the commit.
Finally some advice: you may want to avoid doing this altogether, since it may lead to a lot of merge conflicts when different branches store different values in version.text.

1. main.py
version = open("VERSION.TXT", "r").read()
2. root dir repository
echo 1 > VERSION.TXT
3. add git hook
# cat .git/hooks/post-commit
#/bin/sh
echo "post-commit started"
version=$(cat VERSION.TXT); y=$((version=version+1)); echo $y > VERSION.TXT
4. done
git commit .
git push
