- Improved installation types behaviour

- .onSelChange no longer called when the components page is created
- First section is selected at compile time - changes in .onInit stick
- Added SectionSetSize / SectionGetSize
- Added SetCurInstType / GetCurInstType
- Added InstTypeSetText / InstTypeGetText - ability to change (and add and remove) installation types on runtime
- NSIS_MAX_INST_TYPES is now 32 by default
- InstType texts are now processed ($0, $1, etc. can be used)
- Added /o switch for Section - unselected by default
