Minor amendments and improvements in the scouting logic

It's been a while since I've done any real work on this project so I've made some minor refactoring and put in some improvements to the presentation and player scouting logic, as follows:

• Viewing current squad will tell you the player position as follows:
  GK = Goal Keeper
  DF = Defender
  MD = Midfielder
  SK = Striker
• All player ratings now start at 1

All of the pre-season logic is in

Aside from some refactoring, all of the pre-season logic should now be working, as follows:

1. Instructions dropped - enter your name and goes straight to the game
2. Choose team name (manager and team name max 16 characters, should truncate if over 16 is entered)
3. Scout for players - up to 16 per team, which will be a game limitation (sorry); future versions on more expansive hardware such as the ZX Spectrum will not have such tight limits
4. You may sign 3 keepers, 3 strikers, 5 defenders and 5 mid-fielders max; This helps to balance your squad, but keepers and defenders are somewhat inter-changeable as are mid-fielders and strikers. This I think is the best compromise whilst sticking in the limitations that I'm presented with
5. Note that the randomisation may not always work perfectly, so you may end up with two or more players with the same surname, sometimes the same initial as well.
6. Training sessions will build your player ratings (all players start with zero rating)
7. Don't forget to buy a kit, a squad mini-bus and arrange a home ground.

My initial idea is that you had 7 weeks to build your team and set everything up; if you don't have everything ready in 7 weeks then you will not be able to start the season and that means that you have already failed the game. I might reduce that limit if it's too easy.

Pre-season logic added

At the moment, you're still only able to sign goal keepers, the out field player logic is to be added, but all of the pre-season game logic is in if a little more limited to what I wanted to save space for the main game.

The pre-season aspect of the game may have to be trimmed further, but hopefully I'll be able to save some bytes before doing this.

Alpha to test on real hardware

This is to test on real hardware primarily, and other emulators.

So far, there is the welcome screen in which one may enter one's name; after this, the program should prompt the user to view instructions with Y or N. After either option one should be safely returned to BASIC.

Please report any issues or unexpected behaviour.
