Markdown - better and easier

[AbdealiLoKo]

Making markdown better is one important thing.

I removed the older django-markdown-deux library and used a wrapper for Subdown called misaka which is similar to git's markdown.

But it doesn't have video embedding and image showing. Need to do that by writing own libraries

Added video previews from youtube. Added Link shortening and autolinking in python

[AbdealiLoKo]

Need to add tagging profile with markdown

testing git emoji :

Still need to make a dynamic regex based parser for users.

[AbdealiLoKo]

Made awesome buttons to generate markdowns for links and stuff. But it looks ugly :(

[AbdealiLoKo]

next features : Button to tag a person, dept, etc... Change the markdown for a person, wall, etc based on current doc markdown. (it's better.)

Markdown change - done

Current tasks before closing this issue : Adding a button for it. Adding a reges parses to find them to add them to notif_users

[AbdealiLoKo]

OK, done all major tasks
