Reading translations from json files, translation json files

Added localizer class which reads json files and a translation
for finnish (loc_fin.json). Changing UI element texts to be
read from translation files started.
TODO: change code to allow
adessives used in finnish. Make the whole program use UI element
texts from translationfile. Make view for choosing language.
Version where translation class is done as a singleton

This version does not work, as importing the localizer class
working as a singleton is fucked. Will proceed to tackle the
problem in another way in another branch

Complete translations of english and finnish in json files.

Translations are read with localizer method and used troughout the
program. TODO: make users decide what language is used with either
settings text or UI buttons.
Merge branch 'feature/translations_in_module' into feature/translations
Style changes during peer review

Removed debug print, whitespace
Localizer.loadTranslation properly reloads the translations

Previously the function used a "local" loc variable. By using
the global keyword, we can make it use the loc variable already
defined inside the module. This way it actually reloads the
translations.
