Demonstrated here:

• Create new page at first will zoom out to world: fix #456
• UI change to use proper bootstrap (it can be extended later if not satisfied)
• Layer list loaded via AJAX request --> Map page load faster first, then load layer lists
• UI Feedback when layer is saved. Also options to go to map detail or list or stay in creation page.
• Take basemap options list from LEAFLET settings (the same list in Layer view page). Fix #367
• Thumbnail now with chosen basemap
• Fix #489
• Layer symbology follow default styles defined in the layer itself. fix #406

Demonstrated here:

• Updating/changing existing Map
• Add remove existing map layer in a map
• Change layer order
• Change basemap
• Change title/abstract
• Note that I haven't fixed Map Detail page yet, so the layer order in that page is a mess.
• New thumbnail works with correct order and basemap
