Basic upload field

BasicUploadFieldDefinition renders a field to upload a file to a Magnolia JCR workspace.
The file is stored on the node of the current context of the form (within a dialog or subApp), which could be a content app item, a page or a component of a page.

class: info.magnolia.ui.form.field.definition.BasicUploadFieldDefinition

The basic upload field has three states. You can set properties for each.

Empty is the starting point where no file has been selected. You can select a file with the button or drag it into the box.

In progress displays a progress bar and incremental percentages and uploaded/total ratio.

Completed displays a success notification and summary of file info.

You can use common field properties and the properties in the tables below in a basic upload field definition:

Properties:

`<field name>`	required Name of the field.
`allowedMimeTypePattern`	optional, default is `.` (all types)* Regular expression to filter allowed files by their MIME type. For example, to allow only Excel files set the value to `application.(excel\|xls)`. To allow images only, set the value to `image.`. For more information about the supported pattern, see `Pattern` . For digital asset management MIME types see MediaType.
`binaryNodeName`	optional, default is `binaryNodeName` Name of the subnode that will contain the file binary and related information.
`editFileFormat`	optional, default is `false` When set to `true`, the file extension displayed in the Format field is editable.
`editFileName`	optional, default is `false` When set to `true`, the file name displayed in the Name field is editable.
`maxUploadSize`	optional, default in BasicUploadFieldDefinition is Long.MAX_VALUE and is configurable; however, this seems to be superceded in CosMultipartRequestFilter, where it is set to 2000000000 (2 Gigabytes). Maximum file size in bytes.

Caption properties. Values are typically retrieved from a message bundle.
