Form input components

Reactodia provides basic built-in components to edit entity or relation properties in a form:

Form input component	Description
`<Forms.InputList />`	Form input to edit multiple values in a list of specified single value inputs.
`<Forms.InputText />`	Form input to edit a single value as a plain string with an optional language.
`<Forms.InputSelect />`	Form input to select a value from a predefined list of variants.
`<Forms.InputFile />`	Form input to upload files and display previously uploaded files.

warning

Currently form input components are considered unstable so there might be breaking changes in their API in the future.
