Misc fixes

• Misc SVG dimension fixes: FA EP1, KT EP4&5, NS E04P04 (minor resting of !1021 (merged), left while developing and testing the script)

• Render fix for BR E01P00 and BN E08P02 (BR E01 cover has no text)

• GB - minor updates: gb.po and EP11 (translator's feedback & fix of !1014 (merged) )

• I'm currently polishing and testing some new scripts: svg_dimension_checker.py and extract_custom.py;
• Doing (and testing) some upgrades for find_anomalies.py and regenerate_transcripts.py;

• And I'm experimenting with Python script drag&drop to make transcript generation easier for Windows users:

Context: doing this gives the script 1 command-line argument: 'Z:\\PnC\\webcomics\\ep38_The-Healer\\lang\\en' and it includes all the data needed to generate the transcript.

Edit: Did more upgrades that expected: !1032 (merged)
