added redirect from stdout to stderr for spawned processes to prevent conflicts with the statusbar outputs

Fixed tab formatting in 6 locations where statusbar() is called

Changed output to stdout instead of a file

updated output format for better expansibility and easier parsing

Removed unused variable from statusbar

added statusbar update when tags are updated

Added interface to output information about tags, the currently selected monitor, and the focused client to a file for use by a status bar

add some explanation of output reconfiguration

Hopefully this will help "future us" understand what's going on.

remove hacky code from output-management handler

This functionality belongs in updatemons(), where it can hopefully be
written a bit more elegantly.

commit entire output config, or fail and rollback

The wlr-output-management protocol requires that either all of the
changes from an apply request be applied successfully, in which case a
"succeeded" event is sent, or all of the changes are reverted and a
"failed" event is sent.  As written, this could partially commit
changes, then fail.

Test the changes first (even for an "apply" event), then commit or
rollback as appropriate.

Merge pull request #71 from djpohly/output-layout

call updatemons at the appropriate times

use updatemons as handler for output_layout.change

This should end up firing precisely when we need to adjust our geometry,
rather than us guessing about it based on requests.

unify increment style while we're here

remove unnecessary variable

cleanup on aisle createmon()

Merge pull request #80 from sam-barr/dwl_upstream

Fix Initialization of NetWM Atoms

Merge pull request #77 from djpohly/use-output-direction

Determine monitor order spatially

Fix Initialization of NetWM Atoms

Additionally, variables xcursor and xcursor_mgr are only used
when xwayland is defined, so I make the variables declaration
contingent on whether xwayland is being used

remove now-unneeded monitor position field

use output layout for dirtomon

No need to track our own order; wlroots has a reasonable default for us
already.
