Rewrote documentation

Rewrote some copy to provide more context and link to more GL-related repos, including GL JS. Put the various SDKs in a table so we can show the various CI bot status images.

Integrated target list into the relevant documents. Rewrote large portions of iOS and OS X setup documentation to guide normal developers to more friendly places. Combined some Android documentation.

Moved SDK-specific documentation into platform/. Added a temporary readme in ios/ that points to the one in platform/ios/.

+# Linux
+
+A simple map application and test suite for Linux based on [Mapbox GL Native](../../README.md) and [GLFW](https://github.com/glfw/glfw).
+
+We are using Ubuntu for development. While the software should work on other distributions as well, we are not providing explicit build instructions here.
+
+This process gives you a Linux desktop app built on a Linux host system.
+
+### Build
+
+Install GCC 4.9+ if you are running Ubuntu 14.04 or older. Alternatively, you can also use [Clang 3.5+](http://llvm.org/apt/).
+
+    sudo add-apt-repository --yes ppa:ubuntu-toolchain-r/test
+    sudo apt-get update
+    sudo apt-get install gcc-4.9 g++-4.9
+    export CXX=g++-4.9
+
+Ensure you have git and other build essentials:
+
+    sudo apt-get install curl git build-essential zlib1g-dev automake \
+                         libtool xutils-dev make cmake pkg-config python-pip \
+                         libcurl4-openssl-dev libpng-dev libsqlite3-dev \
+                         libllvm3.4
+
+Install glfw3 dependencies:
+
+    sudo apt-get install libxi-dev libglu1-mesa-dev x11proto-randr-dev \
+                         x11proto-xext-dev libxrandr-dev \
+                         x11proto-xf86vidmode-dev libxxf86vm-dev \
+                         libxcursor-dev libxinerama-dev
+
+Set the environment variable `MAPBOX_ACCESS_TOKEN` to your [Mapbox access token](ACCESS_TOKEN.md):
+
+    export MAPBOX_ACCESS_TOKEN=MYTOKEN
+
+Then, you can then proceed to build the library:
+
+    git submodule update --init
+    make linux
+
+Set an access token as described below, and then run:
+
+    make run-linux
+
+### Test
+
+- `make test-*` Builds and runs all tests. You can specify individual tests by replacing * with their name (e.g. `make test-Sprite.CustomSpriteImages`).
+
+The `zsh` will treat the * in this command as a glob, so you'll need to run
+`make "test-*"` instead.
+
+### Usage
+
+Keyboard shortcuts for testing functionality are logged to the console when the test app is started.
