feat(ui-markdown-editor): heading wysiwyg - #346

Closes #346

This pull request adds the feature of markdown shortcuts for headings. Now we can insert headings in the document with the help of just the #.

• # => H1
• ## => H2
• ### => H3
• #### => H4
• ##### => H5
• ######=> H6

Changes

• A folder called `MatchCases` is added inside the `plugins` folder. This folder is supposed to contain all the upcoming match cases that would be added i.e. code block, ordered and unordered lists, bold, italics etc.
• Right now the folder contains only one file that handles this function.
• A bug in the existing page break shortcut was fixed where it would keep the line where we inserted the ---.
