Get contents without root dir name for single-dir based tables

[georgelemon]

Getting file contents from a single directory table (without root dir name)

echo assetsfile.getAsset("index.html")

Getting file contents from a multi directory table (for multiple -d case)

echo assetsfile.getAsset("templatesdir/index.html")
echo assetsfile.getAsset("js/app.min.js")
echo assetsfile.getAsset("css/app.min.css")

Also, updated the README

I'm on OSX, so I can't tell it works on Windows, but from what I know the / dir separator becomes \
