Improve UI using Bootstrap

[brcb20]

Improve the overall quality of the website and its responsiveness to mobile devices.

Responsiveness:

• bootstrap carousel for slideshow
• rearrange tools, canvas, submission and donation to handle mobile devices
• set min size on canvas and if screen size is smaller then allow scroll + button to expand canvas to full screen size
• Increase font for resolutions >1200px
• "Drag" input on touchscreens, without losing ability to pan

Improvements:

• add reset button to clear canvas
• modify fill functionality to fill within top left / bottom right click
• use tooltips to create a HOWTO guide
• button (or keystroke) to undo last action
• mini color selector still visible when canvas is expanded
• move join us links to nav bar (as icons)
• Create local about page
• Move slideshow and video to about
• add pan button to move around canvas when there is overflow
