Issues to fix

[knochenhans]

• Check behaviour on fresh system ;)
• Complete project adding/loading/saving/closing workflows
• Merging boxes sometimes changes height (probably when overlapping?)
• Page shortcuts like F1 or R only work when Page View has focus
• OCR Editor: Find a way to comfortably fit scan image
• OCR Editor: Scan image sometimes jumps when moved via mouse
• OCR Editor: box item symbol size should be independent of zoom
• Reload tesseract API when language is changed
• Loading images/PDF not showing images directly, reload needed
• Settings not working properly in new projects (only after saving/reloading)
• OCR Editor: Removing and splitting boxes doesn't trigger resorting
• OCR Editor: Analysing pages should remove existing boxes first
• Dehyphenization: check for combinations with "oder", "und" etc.
