Tick list import/export

[nmondollot]

Problems with our current tick list:

• users will lose their data if they delete the app
• users can't easily switch to another device and keep their data

Long term solution: sync with boolder.com account => may take several months to build

Short term solution: import/export tick list with a file The file should work on both iOS and Android

Questions:

• when user imports a file, should we keep the current tick list or replace it? or ask the user what to do?
