+* Add new 'text_limited' widget for TextField, but data are limited to
+10 lines or 500 characters (by default).
+You can change default values by context varibles 'limit_lines' and
+'limit_chars'.
+If data contains more characters or lines, it will be cut.
+Example of usage:
+<field name="some_text_field"
+       widget="text_limited"
+       context="{'limit_lines': 8, 'limit_chars': 400}"
