73 make experiment page frames resize with window

[aobermiller]

Fixes #73

What was changed? Many of the pages in the /experiment_pages directory were modified. Each one only needed a component or two changed. Most commonly an object called 'main_frame' needed to be configured properly

Why was it changed? Many frames did not center themselves in the window or expand to fill the space when the window was resized.

How was it changed?

Most of the changes involved grid configurations. Frames in cage_config_ui.py, experiment_menu_ui.py, map_rfid.py, and select_experiment_ui.py all needed to have grid configurations altered to allow the objects to resize.

@aobermiller What is the progress on this?

[aobermiller]

I only have to configure two more of the pages and then I'm done
