Warning fixes and stuff
Fix mune translation from ini (run/pause) buttion
android buildfix
add s to "Read Framebuffer To Memory (CPU)", "Read Framebuffer To Memory (GPU)" in rc

Unified two keys:
"Read Framebuffer To Memory (CPU)", "Read Framebuffer To Memory (GPU)"
as  "Read Framebuffers To Memory (CPU)" and "Read Framebuffers To Memory
(GPU)"
used in ini file.
Rename "Delete Savedata" & "Delete Game"

I make that because "Delete Game" exists twice (line #69), so the translation can't work.

I rename "Delete Savedata" to looks like the new "Delete Game".
