 Currently there is an option what to do when layer without CRS is loaded,
 still there are no options how to specify new project (map) CRS options.
 There are some other bugs requesting some parts or caused by user-
 unfriendly new project CRS handling (#1355 #363 #2092 #1688 and probably
 others).

 Here is my offer how it could be handled (sorry, no code). Settings->
 Options-> CRS should offer following options:
  * Ask new project CRS (a-la GRASS mode)
  * Use first layer CRS (a-la ArcGIS mode)
  * Use global default CRS
  * Enable OTFR by default (checkbox disabled by default) (#363)

 It will change QGIS default as neither of those options assume WGS84 by
 default as QGIS seems to do now. Still it's possible to mimic current QGIS
 behavior by setting global default to WGS84 and enabling "Use global CRS"
 option with OTFR disabled.

 Bug #1688 was closed with reason "what to do when layer has no CRS?".
 There IS a solution already present in QGIS. QGIS already offers three
 options how to determine layers CRS when layer has no CRS. Just let layer
 CRS detection to work at first and then set project (map) CRS to layer's
 CRS (real one or one determined by "layer without CRS" options).
