Markdown video and audio, supported at client side

* BlogsController.cs: Fixes the Markdown usage of the uploaded
  files:
Files are now renamed by dropping invalid characters and replacing
  spaces by underscores.
An existing destination file is removed at upload.

* showdown.js: Renders audio and video at client side

* to-markdown.js: converts html audio and video to Markdown

* TestByteA.cs: adds a prefix, an underscore, to the test table
  `_testbytea`

* Edit.aspx: Uses the new `showdown` javascript module (that
  previously was named `Showdown`)

* Web.csproj: cleaning

* MarkdownDeep.dll: Renders video an audio

* GruntFile.js: Was pollution
