Android UX improvements

Suggestions for a better user experience of the Android app.

• [x] The details button inside event cards and survey cards is not intuitive. Details should open when the card as a whole is clicked. Either remove the button entirely or replace it with an unclickable image.

• [ ] The return button at the bottom of the EventDetailsFragment and SurveyDetailsFragment is not well thought out, it is too close to the back button. Either move it to the top of the fragment or enable closing the fragment by swiping down. Check out modal bottom sheets.

• [ ] Adding a smooth transition for SurveyResultsDetails image gallery would be a lovely improvement. Resource: https://android-developers.googleblog.com/2018/02/continuous-shared-element-transitions.html

• [ ] Hide SearchFilter component on scroll

• [ ] Consider data preloading during a splash screen. That might result in creating singleton repositories. Maybe add loaders (spinners, progress bars).

• [x] Improve visual hierarchy of text views inside EventDetailsFragment, SurveyDetailsFragment and SurveyResultsDetailsFragment. Add more spacing between different types of information, make text bigger in general.

• [x] Make text selectable and enable navigation on web links.

• [x] Improve search bar behavior. Should focus whenever the rectangle is clicked (currently, gets focus only when search icon is clicked). Also, give the rectangle rounded edges.

Fix focus issues

• [ ] Login screen, e-mail address input field. Remove focus when user touches anything else
• [ ] Search bar. Remove focus when user touches anything else, ESPECIALLY when the active fragment inside viewPager changes
