interface updates. added controls for hemi visibility, surface specularity, and camera projection mode. fixed zooming in orthographic projection. removed zoom lock controls for now, as they are nonfunctional.
i misspelled visible, i am an idiot
added ability to search for colormaps by name, fixes #1.
added image that I forgot, part of colormap search
added tooltips for controls, rearranged some controls to be more sensible (display layers are now in proper order, moved specularity under 'view'), improved hot key responsiveness, slightly adjusted styling
now possible to click on colormap search results to select them
added option that improves performance to get_vox_dist; added function for turning vertex data into voxel data (workaround for missing vertexdata in webshow)
fixed conflicts
fuck, actually fixed merge
now webgl works nicely with multiple display layers
