Remove unnecessary columns first and unwind #012 (octal replacement of
LF) second. Otherwise, important content would be lost.

d964d657ba Allow all non-whitespace chars in program names 
Program names in Posix can contain all characters expect the null byte.
The code allows \S (all non-whitespaces) and spaces in program names.
This excluded some allowed characters like \n, \r and \t. No negative
effects should arise from this.

967d231be5 Use transcrypt --sform to enable string formatting 
The Python string formatting mini language isn't enabled by default.
"{}".format(42) works fine but "{0:x}.format(42)" returns "{0:x}"
instead of "2a" if the mini language isn't enabled.

Newer Red Hat 7 releases changes the output of the OOM a little bit. The
last output line "Killed process" contains the process UID now.

3dc965e8ff Set a single value to several places 
Prior this change items are set to html elements with id of the same
name. Now OOMDisplay._set_item() searches for elements with same-named
id or with item name listed in class attribute.

This allows to set one value to several places to once.

Additional suffixes for pages and kbytes are added in the singular or
plural automatically.
