Changed size.json to deal with the problem where examples (with size blocks w/o dropdowns) don't work due to ordering of parameters in convert() function call. Implemented the workaround mentioned here: https://github.com/waterbearlang/waterbear/pull/632
Added keywords to 4 basic arithmetic blocks
Added front end stuffs for search filter
Fixed search filter textbox extra outline issue in Chrome
Added 2px padding to search filter textbox
Made search filter stay at the top
Replaced search button with background image since button is not really necessary
Added dist files
Used Font Awesome for search and clear icons
Hacked search filter back end
Added drop-down to all relevant blocks in the Size category, and undid the workaround mentioned here: https://github.com/waterbearlang/waterbear/pull/632 to deal with examples not working. Will update examples manually to deal with the socket reordering.
