Automated market resolution (#404)

* Added radio buttons to market creation (non functional)

* Ignoring vs code files

Should this be done in the repo or should everyone using VS Code do that himself globally on his machine(s)?

* Removed 'automatic' resolution

* added union type for resolution

* revert: resolution could be anything here (non binary markets)

* Expanded ChoicesToggleGroup for string choices

* Added combined resolution and required buttons to market creation

* restricted automatic resolution to binary markets

* added automatic resolution to contract

* added automatic resolution to contract overview

* string or number array to mixed array

* created const for resolutions

* Added comments for leading semicolons

* configuration of auto resolution on market creation

* v1.22.19

* v1.0.0

* v0.0.0

* v1.0.0

* v1.22.19

* Mock display automatic resolution

* Revert changes to market creation

* Revert "v1.22.19"

This reverts commit 22f59adc9c.

* Removed resolutiontype from contract creation

* Added auto resolution time to contract

* Auto resolution date editable

* refactoring

* Editable interface for auto resolution

* New edit interface for auto resolution

* Setting of auto resolve date when changing close date

* prohibited changing other peoples markets

* removed unnecessary export

* refactoring

(cherry picked from commit 4de86d5b08)

* Added comments for leading semicolons

(cherry picked from commit 60739c7853)

* Ignoring vs code files

Should this be done in the repo or should everyone using VS Code do that himself globally on his machine(s)?

(cherry picked from commit 944de9398a)

* removed unused imports and variables

* added type for binary resolution

* Prettier

* const for binary resolutions

* using the type "resolution"

* Prettier

* Re-added comment
