sample project

Problem outline:
- An entry control is enhanced to autoreplace (autocorrect) some of the user input while typing
- TextChanged event is used to apply corrections at once
- Approach is similar to the one in this forum post: https://forums.xamarin.com/discussion/43873/xamarin-forms-entry-field-textchanged-event

- Affects Windows and WP8.1 (WinRT platform) and does not affect WP8.0;
- When user types text into Entry, text in Entry is not corrected;
- At the same time, bound model is updated correctly with 'replaced' vlaue.

Sample project is attached:
- Sample project replaces all 'A' with 'Y', and 'a' with 'y' in the text;
- Type text in the Entry, and observe replacements in label.
- Also two buttons added:
-- One modified value in Model, Entry shows correct value with all replacements;
-- Second modifies Entry.Text property directly, and Entry shows correct value with all replacements as well.

Expected behavior:
- Entry displays final, actual value that match the value in the model.
