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.

674ea295a8 Line "Killed process" can contain the process UID 
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.

Old:
    Killed process 6576 (java) total-vm:33914892kB, \
    anon-rss:20629004kB, file-rss:0kB, shmem-rss:0kB

New:
    Killed process 6576 (java), UID 12345, total-vm:33914892kB, \
    anon-rss:20629004kB, file-rss:0kB, shmem-rss:0kB

468991a31b Use textarea placeholder instead of own code 
<textarea placeholder="..."> is more simple that writing own code.
Thereby the own code / logic has been removed.

1ac0bd8fe9 Don't clean elements when set back to defaults 
The elements are not shown, thereby a cleanup isn't necessary. When the
elements are shown again, new values are set and overwrite the old one.

ff725e9235 Fix issue that prevents units from being copied 
Units have been placed with the ::after selector. Content showing with
this pseudo-element can't be selected and copied.

Now the units are automatically added when the value is set.

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.

606d0d6769 Use negative slicing with operator overloading 
Positive numbers in slices works well, but for negative numbers you
have to activate operator overloading. This has a (unknown) speed
penalty.

 * the headline is visible
 * the id attribute is set
