Release 0.7.1

Important fixes for Image and NER labelling

Simple Rectangle, Polygon, KeyPoint or Ellipse tag now works perfect for fast Image labelling without any labels — click and go.

Weird and annoying bugs of text labelling were fixed. They all got restored except the last ones, they were just disappeared:

• broken regions with newlines,
• broken overlapping regions,
• broken regions with special characters,
• broken lengths of regions with whitespaces,
• broken empty regions.

Side panel improved to display more relevant information about regions and relations:

• captured text part is longer now,
• relations highlighted when any of regions in it are selected,
• also relations display number and color of both regions to distinguish between them.

All this covered by tests!
