Allow inclusion of external file in output-wrapper

[GoogleCodeExporter]

This is a feature request:

It would be wonderful, if it would be possible to do something like:

git rev-parse HEAD > version.txt
(writes commit id (like "319a30b7b9eafe2c671a2e7a9f48bbc54cb7baf6") into the 
file)

and then

java -jar plovr.jar build main.json > deploy/index.js

with following line in main.json:

"output-wrapper": "/* Copyright info */\nvar 
MY_PRODUCT_VERSION="%fromfile(version.txt)%";%output%",

This is not currently possible as far as I know and it might come very handy. 
Another possible usage is automatic inclusion of compiled styles into the 
javascript code thus creating applications completely contained in just one 
file.

I am going to mark this as WontFix and instead propose the following workaround:

Change your build process to generate a plovr config such that it includes the 
git commit hash in the "output-wrapper" option. This is actually not that 
difficult if you generate a plovr config that uses the "include" option to 
include your current config in addition to your generated "output-wrapper" 
value. Since you already require an extra step (git rev-parse HEAD > 
version.txt), this is not that much more work.
