Version 0.11 (2014-06-24)

Compared to v0.10, the installer:

• Is built with the Unicode version of Inno Setup.
• Appends Elixir's bin directory to the system's Path environment variable.
• Sets up an Elixir (IEx) icon which longer relies on bin\iex.bat, by using a simpler yet equivalent set of arguments (see this PR.)
• Installs to Program Files by default.
• Is named to indicate that it's a web installer.

I plan on working on these next, but they may or may not appear in a future release:

• The ability to download the latest Elixir release. (Inno Setup's design makes this non-trivial.)
• Upgrading the warning that Erlang isn't installed to an offer to install it.
• Obtaining either a higher-resolution or alternate image for the side banner.
