[elpa] externals/exwm 29f2289 09/12: Consistently name helper windows

[Chris Feng]

branch: externals/exwm
commit 29f2289a750c9cf8f0d5cd968d306ee953a7bc0d
Author: Adrián Medraño Calvo <address@hidden>
Commit: Chris Feng <address@hidden>

    Consistently name helper windows
    
    * exwm.el (exwm--init-icccm-ewmh): Avoid naming the root window.
    (exwm--wmsn-acquire): Use the symbol name in the window name.
    * exwm-systemtray.el (exwm-systemtray--embedder-window): Rename
    `exwm-systemtray--embedder' consistency.
    (exwm-systemtray--init):  Use symbol names in the window name.
