[atsushifx]

On Windows, create boiler plate directory to current working directory.
move this directory to LOCALAPPDATA directory
ref
add: utils/utils.go: boiler plate directory refs "XDG_DATA_HOME"
create boiler directory under the XDG_DATA_HOME directory,
if your os set set XDG Base directory.

add: .editorconfig:
editor tab setting file for go source edit.

Sorry for the drive-by review, but I'd like to point out that directories in $XDG_DATA_HOME, $XDG_CONFIG_HOME, etc. should not be hidden. So it should be something like path.join(XDG_DATA_HOME, 'gibo', 'gitignore-boilerplates')

[atsushifx]

Thank you so match for this quick review.
I change PR to boilerplates directory is not hidden in XDG Base Directories and LOCALAPPDATA.

Hi @atsushifx! Thank you for contributing to gibo. And special thanks for contributing to gibo on Windows.

Can you please remove the editorconfig file from this PR and raise that as a separate PR? I'd like to merge your home dir fix, but I'd also like to think about the editorconfig change a bit more before merging that one.

[atsushifx]

I understood. I make new commit "remove editor config", then this PR have only utils/utils.go file.
please merge this if you have no probllem.

Hey @atsushifx... I thought you'd like to know, I was inspired by your PR to also store the boilerplates in the right place on MacOS too (i.e. ~/Library/Caches), and that in turn lead me to discover go's os.UserCacheDir(). I've incorporated that in bd62924.

[atsushifx]

I read this commit, and I want to make 2 sugesstions.

1. commit bd6924 make boilerplates cache on gibo directory directly. add boilerplates directory to cache , if another data cache by future.

2. I use XDG Base Directory Environment on Windows. But os.os.UserCacheDir() function don't return XDG_CACHE_HOME instead of LOCALAPPDATA, please get $XDG_CACHE_HOME directory on windows , if you can change this.
