Add option to hide-footer

[ichagas]

First, thank you for this module, it is simple and useful.

I made some personal adjustments that I would love to share and make it available in the main repo.

In order to make a simpler UI interaction I added the option hide-footer which can be true or (the standard) false.

Adding this option you create 2 scenarios:

Scenario 1: With Search Bar Turned On
On this scenario:

• The text field add and extra element (X) inside input field in the right corner for clear text (similar to a native iOS)
• The Close/Cancel button gets room in replacement of the regular Clear button

See the example

Scenario 2: Without Search Bar
On this scenario:

• The Close/Cancel option is in the top right position as an X icon

See the example

I only tested the simple selection modal, the multi must be tested but I believe it is save to say it is OK since the changes are minimal.

Great!

I've just made some additional adjustments and perhaps inside the input field the icon ion-close-round looks better than ion-android-close that I picked earlier.
