Fixed #1201

What have you done in this MR?

• Add Seer's Village achievement based on issue raport #1201 (buy something for ticket)
  based on https://runescape.wiki/w/Seers%27_Village_achievements?direction=next&oldid=1470798

Are there any tricky things testers should keep an eye out for?

• Yes, as follows:

• According to the source the store should sell items according to the following table:
  https://runescape.wiki/w/Ranging_Guild?oldid=2047440

Due to the fact that currently in-game the player has a choice of option 1,5,10,X in that shop, which could result in the achievement being awarded after purchasing only 1 item for 5 tickets). I decided that a wizards and witches under the age of 18 could not enter the tri-magic tournament... I mean for items:

• BARB_BOLTTIPS_47 the amount purchased must be greater than 10 to pass the task and for
• RUNE_ARROWS_892 the amount purchased must be greater than 5, to pass the task, not because I want, it's because I don't know how to fix the store.

• I have tested these changes thoroughly.
