Bug 538594 - [Content assist] Default size is too small

This change makes proposal window more suitable for displaying long API
names. Minimum height increased from 10 to 15 elements (width is
depending on that as before, so it is increased accordingly).

Both dimensions will be checked to be not bigger than 1/4 of the
appropriate dimension of the current monitor.
