Title: Fixes #46 - Adds option 'clear_log'

`1` clears log file on instal/update, the default (overwriting the log file)
`0` does not clear the log file on install/update (appending to the log file)

My .vimrc looks like this:

```
let g:neobundle#log_filename=expand('~/.vim/plugin_install.log')
let g:neobundle#clear_log=0
```

This allows me to keep my install log under version control [like so](https://github.com/stephenmckinney/vimfiles/blob/master/vim/plugin_install.log)
