Open multiple independent fields!

[moritzgladigau]

Describe the bug
If the Game Field reaches a bigger size there are more then one fields open which are not connected with each other.
For example at the field 30x16 -> I open the Filed 0x16 and it opens also the field 16x15 most of the time the Problem ist horizontal.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Expert'
2. Click on 'Open Field 0x0'
3. See error

New insight
It seems that the field is partly identical.
The parts marked in the red rectangles are identical.
How dose this happen is the Random Funktion really Random?

Possibly responsible code fromlogic.c

void logic_fill_c(int width, int height, char **field, int numb_of_mine)
{
	logic_place_mine(width, height, field, numb_of_mine);
	logic_place_numb(width, height, field);
}

void logic_place_mine(int width, int height, char **field, int numb_of_mine)
{
	int x, y;
	do{
		x = rand() % width;
		y = rand() % height;
		if (field[x][y] != MINE) {
			field[x][y] = MINE;
			numb_of_mine--;
		}
	} while(numb_of_mine != 0);

}

void logic_place_numb(int width, int height, char **field)
{
	int i, j;
	for (i = 0; i < width; i++) {
		for (j = 0; j < height; j++) {
			if (field[i][j] != MINE) {
				field[i][j] = logic_count_surounding_bombs(width, height, field, i, j) + '0';
			}
		}
	}
