- By default window activation does nothing.
- `activateLogHook` may be used for running some 'ManageHook' for
activated window.
- `activated` predicate may be used for checking was window activated or
not.
As it now consists of a startup hook, a manage hook, an event hook and
a layout modifier, and behaves erratically when any one component is not
included in a user's config (which happens to be the case for all
configs from xmonad-contrib 0.12 since the startup hook is a new
inclusion), it's probably wise to have a single function that adds
all the hooks to the config instead.
NB: This will need a release notes entry anyway!
Correct errors regarding a description of `mappend' for X
Use <+> more often since that's `consistent', and there is no difference since
it's the same as >> when all arguments have the same type (which they do...
otherwise people aren't just combining valid values for that field of the
config).
Most signifigant changes are use unversioned links to external html,
fix a couple of key binding examples, and double quotes that should
have been single.
Set EWMH support atoms and the window manager name in a startup hook,
rather than in the log hook: the log hook occurs far too frequently
for it to make sense to set constants with it.
