Some suggestions for the Calendars plug-in

[kajaji]

These are some suggestions to improve the readability of the Calendars plug-in:

• The link provided here is:
  

  stellarium/plugins/Calendars/src/gui/CalendarsDialog.cpp

  Line 206 in 0f12e9b

  .toHtmlEscaped().replace(a_rx, "<a href=\"https://doi.org/10.1017/9781107057623\">\\1</a>") + "</li>";

  
  is not working. I found the correct link as:
  https://doi.org/10.1017/9781107415058

• I suggest for this line:
  return QString("%1, %2 - %3 (%4) - %5 A.H.")
  here:

  stellarium/plugins/Calendars/src/IslamicCalendar.cpp

  Line 93 in 0f12e9b

  return QString("%1, %2 - %3 (%4) - %5 A.H.")

  
  to add "A.H." to the translation strings with guidance for translators that A.H. stands for "after hegira" meaning the year prophet Mohammad (Peace be upon him and all prophets) migrated from Mecca to Madinah.

• Similarly for:
  return QString("%1, %2 - %3 (%4) - %5 A.P.")
  here:
  

  stellarium/plugins/Calendars/src/PersianArithmeticCalendar.cpp

  Line 95 in 0f12e9b

  return QString("%1, %2 - %3 (%4) - %5 A.P.")

  
  to add "A.P." to the translation strings with guidance for translators that A.P. means Anno Persico/Anno Persarum = Persian year

• Similarly for the Hindu Calendars
  return QString("%1, %2 - %3 (%4) %5- %6 K.Y.")
  here:
  

  stellarium/plugins/Calendars/src/OldHinduLuniSolarCalendar.cpp

  Line 86 in 0f12e9b

  return QString("%1, %2 - %3 (%4) %5- %6 K.Y.")

  
  to add "K.Y." to the translation strings with guidance for translators that K.Y. stands for Kali Yuga.

• Calendars display in right-to-left languages:
  The calendar columns are displayed left-to right. If the calendar name column can be displayed first (to the right), it will look better and more logical for right-to-left language users.

Thanks
