Rename Project Euler directories and other dependent changes (#3300)

* Rename all Project Euler directories:

Reason:
The change was done to maintain consistency throughout the directory
and to keep all directories in sorted order.

Due to the above change, some config files had to be modified:
'problem_22` -> `problem_022`

* Update scripts to pad zeroes in PE directories

+Problem:
+
+Comparing two numbers written in index form like 2'11 and 3'7 is not difficult, as any
+calculator would confirm that 2^11 = 2048 < 3^7 = 2187.
+
+However, confirming that 632382^518061 > 519432^525806 would be much more difficult, as
+both numbers contain over three million digits.
+
+Using base_exp.txt, a 22K text file containing one thousand lines with a base/exponent
+pair on each line, determine which line number has the greatest numerical value.
+
+NOTE: The first two lines in the file represent the numbers in the example given above.
