export to ODT fails ...

```
Server error: /home/ozn/wikis/wikidata/static/Error_Building_The_Work_Space.jpg: openFile: does not exist (No such file or directory)
```

as a work around I copied "static" into wikidata, and put the images inside it.

```
$ ls wikidata/static/
css Error_Building_The_Work_Space.jpg screenshot.1.jpg Target_Editing.jpg
Empty_Target.jpg img Target_Content.jpg
```

The problem with this work around is that, new images are uploaded in `wikidata` and not to `wikidata/static/`.

I have no clue about Haskell. But, I think this is because in the file `Handlers.hs` the variable `dropWhile` is hard coded:

```
uploadFile :: Handler
uploadFile = withData $ \(params :: Params) -> do
let origPath = pFilename params
let filePath = pFilePath params
let wikiname = normalise
$ dropWhile (=='/')
```

IMHO, it would make sense to make this a configurable option.
