msvc: Fix some compiler warnings

Browse Source 
In particular, the compiler issues the following warnings:

    src/revobject.c(29) : warning C4305: 'initializing' : truncation \
        from 'double' to 'const float'
    src/revobject.c(56) : warning C4244: '=' : conversion from \
        'const float' to 'unsigned int', possible loss of data
    src/revobject.c(149) : warning C4244: '=' : conversion from \
        'const float' to 'unsigned int', possible loss of data

In order to suppress the warnings we change the type of max_load_factor
to double, rather than change the initialiser to 0.65f, and cast the
result type of the expressions to 'unsigned int' as expected by the
assignment operators. Note that double should be able to represent all
unsigned int values without loss.
