New format for coloring

[WPMGPRoSToTeMa]

Current format of coloring is too unreadable and uses control chars (some plugins can use \ as ctrlchar, this can lead the problems).

I suggest a new format for coloring that uses curly braces: {color}:
{yellow}, {none}, {default}, {red}, {green}, {blue}, {gray}, {grey}, {white}
Example:
ChatPrint(0, "{red}This {green}is {none}some {green}message");

Advantages:

• more readable
• doesn't use ctrlchars

Disadvantages:

• curly braces now should be escaped everywhere (by using {{ and }}), ChatPrint_EscapeString is more actual now
• it is too long, what about shorten form?

Short form:
{r}, {g}, {b}, {w}, {y}, {d}, {n}
Example:
ChatPrint(0, "{r}This {g}is {n}some {g}message"); // The short form looks more good for me

Disadvantage of short form:

• for gray we should use white ({w}), because green uses {g}

Problem:

• it is too hard to use ChatPrint_EscapeString everywhere, what about a new escape function that returns string as return value? (array return)
