[#72] Remove package ngx-markdown (#145)

ngx-markdown is a markdown formatter/parser that was ported over from
CATcher. As WATcher does not use any form of markdown parser, this
package currently does not serve any use in WATcher.

Therefore, let's remove the unused package and the related components.
