Add miniphrase

[yurytsoy]

Tricky parts:

• Miniphrase contains collection of phrases that are generally not connected to each other. Difficult to group. Some options:
  • Group by alphabet: A-B; C-D; ...
  • Group by type: questions; exclamations; information; standard phrases; ...
• Number of phrases is quite large, placing all of them in one exercise could be not very meaningful.
