Merge branch 'release/0.4.1' into develop
Add an installer for the msysgit environment

This installer:
- detects the Git installation path
- checks prereqs (git, getopt.exe)
- delete old gitflow install
- install gitflow files

"Access denied" errors are detected and the user is given advice in that case (
use full administrator rights).
Update README for msysgit to use the new installer
Fixed require_tag_absent to not break when the list of tags contains an ambiguous entry, e.g. looking for "1.0.1" in "0.1.0 0.1.1 0.1.2 1.0".
- Removed quoting in has $SOME_BRANCH $(get_remote_branches), as the check was always false
- Added fetching develop branch from origin when fetch flag is on in feature finish
release: start subcommand takes an optional base as well
