Character Frequency Counter
Write a program that counts the frequency of each character in a given string. Your program should ignore spaces and be case-insensitive. The output should be a list of characters and their counts, each on a new line in the format 'char:count'. Characters should be printed in alphabetical order. If a character appears more than once, its count should be represented as the total number of appearances.
Example Input:
Hello World
Example Output:
e:1
H:1
l:3
o:2
r:1
W:1
