Add support for alias notes

[kevinslin]

Context

There are some cases when you want the same note to have multiple paths. See this and this

Proposal

Introduce note aliases, a way to map the same note to multiple paths.

Example

Say you have the following note

• python.lib.pandas.md

---
title: Pandas 
desc:  > 
    pandas is a fast, powerful, flexible and easy to use open source data analysis and manipulation tool
aliases: 
  - ds.tools.pandas # ds -> data science
  - pro.pandas # pro -> project
---
...

• 1. This note would be able to be queried via lookup using any of the following queries:
  • python.lib.pandas
  • ds.tools.pandas
  • pro.pandas
• 2. Any wikilinks with the above three terms will also all resolve to python.lib.pandas
• 3. The Dendron Tree View will show all three notes. Clicking on any will resolve to python.lib.pandas
• 4. The Note Graph View will follow the same behavior as the tree view

I like this idea a lot.

The main concern I have is if two notes have the same alias, where a file name conflicts with the alias name in the tree view.

Right now, in this case, I think the file name should win out, and possible the file name could include a link to the alias notes, possibly as a metadata, or transcluded in the body of the document. Perhaps by default, if an alias is created, a note should be created with the file name corresponding to the tree node with the aliased note transcluded in it. There are a lot of ways to approach this.

Also, what would be the benefit of this approach as opposed to create a note that transcludes or links to the existing note? I'm not even sure if there would be benefits in the graph view.(#1916 (comment)). #1916

@sahil48 On the topic of what is the benefit of just regular link, there is a huge benefit between just the link since alias would allow you to open the note right away instead of having another navigation hop to get from a stubby alias note to the actual note which contains the content.
