Fix line spacing for plaintext previews ()
Adding `<br>` between each line is not necessary since the entire file
is rendered inside a `<pre>`

Ensure that plain files are rendered correctly even when containing ambiguous characters ()
As recognised in  the rendering of plain text files is somewhat
incorrect when there are ambiguous characters as the html code is double
escaped. In fact there are several more problems here.

We have a residual isRenderedHTML which is actually simply escaping the
file - not rendering it. This is badly named and gives the wrong
impression.

There is also unusual behaviour whether the file is called a Readme or
not and there is no way to get to the source code if the file is called
README.

In reality what should happen is different depending on whether the file
is being rendered a README at the bottom of the directory view or not.

1. If it is rendered as a README on a directory - it should simply be
escaped and rendered as `<pre>` text.
2. If it is rendered as a file then it should be rendered as source
code.

This PR therefore does:
1. Rename IsRenderedHTML to IsPlainText
2. Readme files rendered at the bottom of the directory are rendered
without line numbers
3. Otherwise plain text files are rendered as source code.

Switch Unicode Escaping to a VSCode-like system ()
This PR rewrites the invisible unicode detection algorithm to more
closely match that of the Monaco editor on the system. It provides a
technique for detecting ambiguous characters and relaxes the detection
of combining marks.

Control characters are in addition detected as invisible in this
implementation whereas they are not on monaco but this is related to
font issues.

Add more linters to improve code readability ()
Add nakedret, unconvert, wastedassign, stylecheck and nolintlint linters to improve code readability

- nakedret - https://github.com/alexkohler/nakedret - nakedret is a Go static analysis tool to find naked returns in functions greater than a specified function length.
- unconvert - https://github.com/mdempsky/unconvert - Remove unnecessary type conversions
- wastedassign - https://github.com/sanposhiho/wastedassign -  wastedassign finds wasted assignment statements.
- notlintlint -  Reports ill-formed or insufficient nolint directives
- stylecheck - https://staticcheck.io/docs/checks/#ST - keep style consistent
  - excluded: [ST1003 - Poorly chosen identifier](https://staticcheck.io/docs/checks/#ST1003) and [ST1005 - Incorrectly formatted error string](https://staticcheck.io/docs/checks/#ST1005)

Don't treat BOM escape sequence as hidden character. ()
* Don't treat BOM escape sequence as hidden character.

- BOM sequence is a common non-harmfull escape sequence, it shouldn't be
shown as hidden character.
- Follows GitHub's behavior.

Add warning for BIDI characters in page renders and in diffs ()
Fix 

Given the comments I've adjusted this somewhat. The numbers of characters detected are increased and include things like the use of U+300 to make à instead of à and non-breaking spaces.

There is a button which can be used to escape the content to show it.
