[Collection Creation] - Update Collection Details

[ggirotto]

Dependent of #215, #217 and #218.

Summary

Creates Details tab content from Update Collection Page.

Business Rules

• The details content must be overridable by an existing collection content, since it may be used to update an existing collection.
• The collection name field must be an alphanumeric field with maximum length of 30.
• The tags field is an optional field (can have no tags) and must support at most 5 tags.
• The collection description is an optional alphanumeric field with maximum length of 1000 characters.
• All fields must be non-empty strings, and those that are obligatory (name) must have at least 1 character.

UI special behavior

• The description field must update its height based on the content.
• When editing a field the user must be able to "jump" to the next one by tapping "Next" key in the keyboard (we must control the fields focus).
• The tags field must wrap the tags if they are larger that the screen width (just like Wrap Widget works)
