Add support for tab completion in bash.
Summary:
From https://github.com/facebook/buck/pull/54.
When the bash_completion script is loaded, the user
can use the tab key to automatically complete the name of the
`buck command`, or if there are multiple commands beginning with
the same letter(s) suggest commands to use.
Test Plan:
Install the completion script:
$ ./scripts/bash_completion
Suggestion of all available commands:
$ buck
audit build cache clean install project targets test uninstall
Suggestion of available commands with given starting letter:
$ buck c
cache clean
Completion of command with given starting letter
$ buck b
("b" is auto-completed to "build")

+# #########################################################################
+# This bash script adds tab-completion to buck.
+#
+# Testing it out without installing
+# =================================
+#
+# To test out the completion without "installing" this, just run this file
+# directly, like so:
+#
+# . ~/path/to/bash_completion
+#
+# Note: There's a dot ('.') at the beginning of that command.
+#
+# After you do that, tab completion will immediately be made available in your
+# current Bash shell. It will not, however, be available next time you log in.
+#
+# Installing
+# ==========
+#
+# To install the completion, point to this file from your .bash_profile, like so:
+#
+# . ~/path/to/bash_completion
+#
+# Do the same in your .bashrc if .bashrc doesn't invoke .bash_profile.
+#
+# The settings will take effect the next time you log in.
+#
+# Uninstalling
+# ============
+#
+# To uninstall, just remove the line from your .bash_profile and .bashrc.
