Add bin folder to .gitignore

In Eclipse preferences under the Team -> Git -> Project section, if the
"Automatically ignore derived resources by adding them to .gitignore"
option is enabled (which is the default), Eclipse will automatically
add "/bin/" to the .gitignore file.

Update the .gitignore file with this change to prevent Eclipse from
causing unexpected modified files in the git status.
