Run this script from the root of the repository to update all translations from
transifex.
It will do the following automatically:

- fetch all translations using the tx tool
- post-process them into valid and committable format
- remove invalid control characters
- remove location tags (makes diffs less noisy)

TODO:
- auto-add new translations to the build system according to the translation process
- remove 'unfinished' translation items

The "Transifex client" (see: http://support.transifex.com/customer/portal/topics/440187-transifex-client/articles)
will help with fetching new translations from Transifex. The Transifex configuration (`.tx/config`)
is used to fetch new translations from Transifex. The configuration for this client (`.tx/config`)
is part of the repository.

It is also possible to directly download new translations one by one from the Transifex website.
Do not directly download translations one by one from the Transifex website, as we do a few
postprocessing steps before committing the translations.

### Fetching new translations

1. `tx pull -a`
1. `python contrib/devtools/update-translations.py`
2. update `src/qt/bitcoin.qrc` manually or via
`ls src/qt/locale/*ts|xargs -n1 basename|sed 's/\(bitcoin_\(.*\)\).ts/<file alias="\2">locale\/\1.qm<\/file>/'`
3. update `src/qt/Makefile.am` manually or via
