Update some stale information in README.md
- Remove reference to `~/.emscripten`. We no longer use the home
directory to store config information by default, either in
emscripten or in emsdk.
- Remove some references to `The Emscripten Command Prompt`. While I
suppose this is referring to the windows-only `emcmdprompt.bat`, and I
suppose it means "any shell where `activate` has been run", I think
its more clear to simply avoid using the term.

-By default, Emscripten locates all configuration files in the home directory of
-the user. This may be a problem if you need to simultaneously build with
-multiple Emscripten compiler versions, since the user home directory can only be
-configured to point to one compiler at a time. This can be overcome by
-specifying the '--embedded' option as a parameter to 'emsdk activate', which
-will signal emsdk to generate the compiler configuration files inside the emsdk
-root directory instead of the user home directory. Use this option also when it
-is desirable to run emsdk in a fully portable mode that does not touch any files
-outside the emsdk directory.
