* src/pic/ralloc.h: applied patch from Slade Rich;
added support for multiple code pages and multiple RAM banks on the
PIC 14 port. The ASM files now no longer simply assume all the
code / RAM are in the same page / bank. This means the linker can
safely allocate code/RAM of separate ASM files to different pages/banks.
* doc/sdccman.lyx: added Slade's tips
