Exit list and copy list name functionality added

The list name (localToken) was added on the screen so user know what is shopping list name. It was decided that user should be able to leave existing list if needed, for this one 'exit button' was added with confirmation window, when user confirms localStorage will be cleaned and user will be pushed to the Home page. As user needs to save existing shopping list name a 'copy button' was added - it copies a list name (localToken) when it clicked, so user can paste and save it somewhere else. Functionality to enable "email localToken" still in progress. Disregard the styles: will be updated accordingly with listView style.

Closes #36 #39 #45

Acceptance Criteria

Three word token == shopping list name should be displayed on the screen
User should be able to leave current shopping list to join another one. User should be warned that to keep access to shopping list three word token should be saved and used to enter the list back
Copy list name functionality for easier copy/save process

Confirm that three word token displayed on the page and it is the same that is saved in localStorage. Click the 'copy' button and paste somewhere and confirm that it is the same three word token. Click the 'exit' button, confirmation window should pop up, if 'cancel' - listView page still open, if 'confirm' - home page will be opend and localStorage will be cleaned.
