Set default mode to uploaded configuration files

[jdeppe-pivotal]

scp sets permissions to the uploaded tmp file by default to 0400 and PR #26 caused them to be copied to the actual destination. So set the file mode always, defaulting to 0644.

I didn't have time to test well your previous PR (#26) but I already thought setting the default mode to 0644 as I was afraid the umask might be something else. I had already opened a tab to file an issue about it. =)

So would you like to change this PR to set the default mode in Action::Base#write_config? No obligation, I'll do it later today otherwise.

Oh, just realized this is not because of umask, but because scp sets the strict permissions. The same solution sounds the best to me though.

I think this is what you mean.

BTW, thanks for this plugin. It's a life saver when you're behind a corporate proxy and can't go sit in the coffeehouse all day. :)

Yep! I'll merge now (again without testing ;)). As soon as I'm done with the day job I'll try to prepare a point release.

Thanks for the thanks! =)
Funny thing is that my own original need was just to configure Apt to use apt-cacher-ng. But it really seems that the corporate proxies make a much bigger market. ;)

Btw, I edited the issue title and description.

@jdeppe-pivotal Just a heads up that I released v0.5.2 last night including these fixes. Thanks for contributing!
