Multiple constraints in config and Tcl data

Browse Source 
**Note**: This new feature requires a modification of the SQLite database used by Flatisfy. If you don't care about your current database, you can just remove it and do a reimport. Otherwise, you should do the following modifications manually:

* Add a [flatisfy_constraint](ed7e9dfc1a/flatisfy/models/flat.py (L89)) VARCHAR field in the flats table.
* Create [this table](ed7e9dfc1a/flatisfy/models/public_transport.py (L24-32)) for public transport data and [this one](ed7e9dfc1a/flatisfy/models/postal_code.py (L24-34)) for postal codes data.

Closes #58

## Adding new data files
If you want to add new data files, especially for public transportation stops
(to cover more cities), please follow these steps:
1. Download and put the **original** file in `flatisfy/data_files`. Please,
use the original data file to ease tracking licenses and be able to still
have a working pipeline, by letting the user download it and place it in
the right place, in case of license conflict.
2. Mention the added data file and its license in `README.md`, in the
dedicated section.
3. Write a preprocessing function in `flatisfy/data_files/__init__.py`. You
can have a look at the existing functions for a model.
Thanks!

form. Beware that `time` constraints are in **seconds**.
You can think of constraints as "a set of criterias to filter out flats". You
can specify as many constraints as you want, in the configuration file,
provided that you name each of them uniquely.
## Building the web assets
If you want to build the web assets, you can use `npm run build:dev`
(respectively `npm run watch:dev` to build continuously and monitor changes in
source files). You can use `npm run build:prod` (`npm run watch:prod`) to do
the same in production mode (with minification etc).
## Tips
### Running with multiple configs
Let's say you are looking for a place in different places far apart (e.g. both
a house in the country for the weekends and a place in a city for the week),
you can use multiple configuration file (in this case, two configuration
files) to define everything.
Indeed, `serve` command for the web app only use a subset of the
configuration, basically only the `data_directory`, `database` URI and so on.
So, you are free to use any config file for `serve` command and still run
`import` commands multiple times with different configuration files, for
different housing queries.
This is kind of a hack on the current system, but is working!
*Note*: You can also use this tip if you are living in a city split across
multiple postal codes and want to implement constraints such as "close to
place X if postal code is Y".
