[EVENTVWR]

[EVENTVWR]
- Display 3 different "types" of logs in the tree: "system logs": Application, Security, System, that are the minimal set of standard logs present on NT systems; "application logs": all the other logs, that are available to the event log service (both "system" and "application" logs are registered in the registry, under the "EventLog" service key). Finally comes the "user logs" that consists in all the log files that are manually opened by the user inthe event log viewer.
- Use 'PEVENTLOGRECORD' instead of 'EVENTLOGRECORD *'.
- Don't hardcode the buffer length values in the size parameters used in the GetEventUserName function.
- Merge both GetDisplayNameFile and GetDisplayNameID helpers into a single GetDisplayNameFileAndID function, since the former two were always called in tandem.
- Forbid editing the labels of the tree root nodes "system"/"application"/"user" logs.
- Splitter bar: set the cursor only when it is on the bar, not when it is above the status bar...
- Resize the status bar only in WM_SIZE events.
- Remove few dead code.
