Filesystem module should allow reading and writing binary files.
CommonJS proposal: http://wiki.commonjs.org/wiki/Filesystem/A.
It's called "raw".

the "mode" string is now properly parsed, and not only the first
char evaluated. This allows us to do fancy things like
fs.open(file, "rw+"); // read/write/append
Furthermore .read() is adapted such that it will always return the
full file contents, no matter where we have seeked to before (i.e.
by passing + we seek to the end, hence read() would always return
an empty string).
To open a binary file, pass "b" in the mode string to fs.open, e.g.:
fs.open(file, "rb"); // read binary
fs.open(file, "wb"); // write binary
fs.open(file, "rwb+"); // read/write binary, append
alternatively, one can use these shortcuts:
fs.write(file, contents, "b"); // write binary
fs.read(file, "b"); // read binary
Unit tests are extended and the echoToFile.js example fixed (it did not
close the file, which lead to the contents never getting written
on-disk since flush() is never called).
Also note that the FileSystem::open method was cleaned up and at least
one memory leak (if QFile* could not open) was fixed. The code should
now also be more C++-like.

use QString instead of QByteArray for raw binary data
QByteArray is simply unusable in JavaScript, since functions like
e.g. window.btoa expect a string. Also there is no sane way to
create a byte array in javascript, as ArrayBuffer e.g. is not
supported by QScript (at least there is no conversion in place).
If we use QString and some custom read/write code this all works
as expected though, we can use window.btoa to base64 encode binary
data and we can create random binary data using String.fromCharCode
also adds a unit test

make it possible to read/write raw/binary files
this adds File::readRaw and File::writeRaw functions,
as well as 'shimmed' versions FS::readRaw and FS::writeRaw
these functions directly use QFile and QByteArray instead of
QTextStream and QString, making it possible to read and write
binary data, e.g. images and such.
