Bundle node for APM rather than using system one

[keirlawson]

APM only supports node 0.10.x versions so if the globally installed node version is something newer (in my case 0.12.7), package installation and other things that depend on APM will not work. The solution that the atom devs seem to favour is bundling the node executable rather than linking to the system version.

Hi.
My decision on link node to distribution was:

• The default node version on target distributions (fedora, redhat, centos) is 0.10.x;
• The process used to incorporate node inside atom is downloading from internet. This binary not compiled inside rpmbuild a process, and without system libs was rejected by rpmbiuld;
• Decrease size of package to distribute;

The second one is main reason to not put node inside atom package. But i will try again.

To use another version of node, on my case, i don't overload the default node, but i use "nvm" (Node Version Manager). Using this i can use a lot of versions of node on same os.
