feat: Add from:me search functionality

[surfdude29]

Describe the feature you'd like to request

I would like Graysky to add from:me search functionality, similar to that which was recently added to the official app.

Describe the solution you'd like to see

The user would be able to search their own posts by typing "from:me" instead of typing "from:[username]".
