Kalle Olavi Niemitalo 23fd2d58f4 Make struct action const
With GCC 4.3.1 on i686, this changes the sizes of sections as follows:

section            before       after   change
.text              682428      682492      +64
.rodata            212668      216352    +3684
.data               58092       54444    -3648
.debug_info       1482388     1482472      +84
.debug_abbrev      153714      153723       +9
.debug_line        272299      272319      +20
.debug_loc         540394      540372      -22
.debug_ranges      113784      113792       +8
Total             3917695     3917894     +199

The surprising .text change comes from src/config/dialogs.o.
Some of that is in get_keybinding_text(), where GCC changes the
order of basic blocks and apparently misses some optimizations.
