* First take on removing erroneous path characters

Paths should not accept trailing slashes or hashtags. This is a first attempt at nullifying those.

* Use rules to verify path before acceptance

Use Regex and rules to verify paths before acceptance

* Rules to prevent any leading or trailing slashes

* Complex slug for regex on path, but it elminates special chars

* Added yarn.lock to .gitignore

* Maybe we do want yarn.lock afterall

* Adding yarn.lock

* Move Regex pattern outside of export

When using inline math ($e^{-x^2}$) the curly braces are interpreted as
attributes by markdown-it-attrs. Since most of the times they are not
valid attributes they simply get removed.

This patch escapes the curly braces (the default attribute delimiter),
fixing the KaTeX rendering errors.

It would be nice to simply skip that rule for `katex_inline` block types
but as far as I know markdown-it-attrs doesn't have such an option.

Fixes #1581

Fix for #2062. Using token.string only captured the character at the cursor. Now using the cursor location to determine suitable search text. Also corrected syntax issue where suggestion removed opening link parenthesis.

* Fix: Fix word-wrap in markdown editor

Overwrite css-property 'work-break: normal' for '.CodeMirror-wrap
pre.CodeMirror-line', which lead to words not wrapping correctly,
with 'word-break: break-word' to properly wrap words.

* Add rule for 'p.line' under .editor-markdown-preview-content

Add 'overflow-wrap: break-word;' for line in the preview of the markdown editor, so the preview properly wraps and does not overflow.
