Moved text below icon for search panel

[RyancRiv]

Description

When searching for rules in the search panel, the buttons sizes used to not be regulated and the text was on the side making the panel look disorganized. This was because in the searchForRule function, when buttons were created from the found rules there was no changes to the preferred size of the button. I added this code to make the preferred size 150 x 150 and I also moved the text to be at the bottom of the button and centered, like in the other panels.

In the searchForRule function, when similar rules were found to the search result and a new button was created; I added code to change the preferred size using setPreferredSize, and I changed the positioning of the text using setHorizontalTextPosition and setVerticalTextPosition.

Closes #432
