Update ncp to 0.2.6 and possibly add config options

[swbiggart]

I've been having intermittent build issues where sometimes the contents of app/assets fail to be moved correctly. I still haven't narrowed down the problem, but in doing my debugging I noticed that the file permissions (owner/group) were inconsistent after ncp moves the files.

I then looked at the ncp github and saw that the issue was fixed in the most recent version 0.2.6:

AvianFlu/ncp#13

It would be nice if brunch used this newest version.

Also, ncp has the ability to use a few flags that would be helpful for debugging:

ncp [source] [dest] [--limit=concurrency limit] [--filter=filter] --stopOnErr

that would be nice if I could pass to brunch directly (instead of me hacking up source to debug)

Thanks!

How the flags should be passed in your opinion? Maybe brunch just enable stopOnErr by default?

[swbiggart]

Well, the flag I was most interested in was the --limit option, cause I thought that I was running into an issue with too many concurrent files open (which, when I realized 16 is the default, came to the conclusion that wasn't the issue).

I like the idea of stopOnErr by default, or maybe when BRUNCH_DEBUG=1 is set.

One option for setting ncp options could be in the config.coffee file, which has buildPath and other compile/asset/plugin config options.

Fixed in 1.0.1 (npm update -g brunch).

As for stopOnErr — brunch currently doesn't stop on errors so I think it should be consistent here too.
