Multi is the default api for methods, it is not necessary to explicitly
decorate methods with it, adds clutter and most people use it because
they see that the rest of the code uses it.
Done with `find . -type f -name '*.py' | xargs sed -i '/@api.multi/d'`
Instead of forcing the creation of iap account to consult its balance,
since it will most likely be 0 at creation, we only generate it on
explicit user action (e.g. Click to recharge the account).
