v1.04

• Added PIC24/dsPIC support;
• PIC32: Core Software Interrupt is now handled by the kernel completely,
  application shouldn't set it up anymore. Refer to the page \ref
  pic32_details.
• Refactor: the following symbols: NULL, BOOL, TRUE, FALSE now have
  the TN_ prefix: TN_NULL, TN_BOOL, TN_TRUE, TN_FALSE. This is
  because non-prefixed symbols may be defined by some other program module,
  which leads to conflicts. The easiest and robust way is to add unique
  prefix.
• Refactor: PIC32 MPLABX project renamed from tneo.X to
  tneo_pic32.X.
• Refactor: PIC32 ISR macros renamed: tn_soft_isr() ->
  tn_p32_soft_isr(), tn_srs_isr() -> tn_p32_srs_isr(). It is much
  easier to maintain documentation for different macros if they have
  different names; more, the signature of these macros is
  architecture-dependent. Old names are also available for backward
  compatibility.
