Release v0.6.2

On the various flavors of bash for Windows kubectl won't resolve as the binary is kubectl.exe.

+- Install bash/zsh/fish [completion scripts](completion/).  
+  - For zsh:  
+    The completion scripts have to be in a path that belongs to `$fpath`. Either link or copy them to an existing folder.  
+    If using oh-my-zsh you can do as follows:
+    ```bash
+    mkdir -p ~/.oh-my-zsh/completions
+    chmod -R 755 ~/.oh-my-zsh/completions
+    ln -s /opt/kubectx/completion/kubectx.zsh ~/.oh-my-zsh/completions/_kubectx.zsh
+    ln -s /opt/kubectx/completion/kubens.zsh ~/.oh-my-zsh/completions/_kubens.zsh
+    ```  
+    Note that the leading underscore seems to be a convention.  
+    If not using oh-my-zsh, you could link to `/usr/share/zsh/functions/Completion` (might require sudo), depending on the `$fpath` of your zsh installation.  
+    In case of error, calling `compaudit` might help.
+  - For bash:
+    ```bash
+    git clone https://github.com/ahmetb/kubectx.git ~/.kubectx
+    COMPDIR=$(pkg-config --variable=completionsdir bash-completion)
+    ln -sf ~/.kubectx/completion/kubens.bash $COMPDIR/kubens
