Now with actual malloc/free implementations. Had to drop back to -O1
optimization because the ed25519 signature test broke with -O2. :(
Closes#153
The toolchain install and build process, for reference:
```
wget https://s3.amazonaws.com/mozilla-games/emscripten/releases/emsdk-portable.tar.gz
tar xvfz emsdk-portable.tar.gz
cd emsdk-portable
./emsdk update
./emsdk install latest
./emsdk activate latest
source ./emsdk_env.sh
cd ../TextSecure-Browser
grunt build
```
This is a whitespace-only change. The diff is best viewed
with the `--patience` flag.
Some component library sources include trailing whitespace and carriage
returns which were excluded from these compiled files, (but somehow
still included in the final libtextsecure build). Although superfluous,
excluding these characters from these files means that I end up with
spurious changes whenever I rebuild them.
