Add Ramdisk Support

[ryanelian]

instapack should add ramdisk support for building JS files (and possibly CSS files) in development + watch modes, including serve mode.

For example:

ipack set temp Z:\

then...

ipack -T

Where Z:\ volume is a directory path made by any ramdisk software:

• https://sourceforge.net/projects/imdisk-toolkit/ (Open Source)

There are also equivalent tools in Linux and Mac OS land:

• https://unix.stackexchange.com/questions/66329/creating-a-ram-disk-on-linux
• https://gist.github.com/htr3n/344f06ba2bb20b1056d7d5570fe7f596

During build, the JS output folder will be deleted and replaced by a symlink to a folder inside this ramdisk volume. This speeds up development build performance especially during write-heavy serve mode!
