Modified grid classes to use the rem unit to allow for scaling up pages.
Modified all fields to use the rem unit to allow for scaling (rem unit is still not implemented on images however).
Fixed bug - borders of fields were not updated to use the rem unit.
Images are now resized/re-positioned using the rem unit, they can scale up during document exporting.
Fixed bug - image copy function referenced an incorrectly named variable.
Changed font sizes for text boxes.
Made input text boxes longer, made formatted number groups scrollable.
Created new dialog menu that pops up when the document is being exported.
