SQW: fix multiple dtor calls and DB close

sql_well class doesn't support copying, but frac_comp_builder made
explicit copies of passed sql_well object.
SQW: add well source data tag to wells table
SQW: fix indexes ambuigity warning in frac_comp_buider::build_cache()
common_alg: add well log mean interp algo
WPI: fix multi-well intersection algo build with MSVS

Array of intersect_base instances are stored now as std::list instead of
more convinient std::vector,, because VS requires operator= for elements
of std::vector.
-- Update MSVS project files
WPI: fix compile error related to xbricks vector -> list replacement
alg: wix well log mean interp algorithm

common_types: add useful functions to property iface

These functions already been implemented but for Python only. Make them
available via interface.
common_types: trajectory now contains properties object just like GIS
common_types: fix traj properties init & serialize

Properly create empty props in ctor & restore 'em in from_str()
sql_well: change interface and refactor well traj and log saving and reading

Idea is that primary storage for well logs is well_logs table,
where each log is stored separately.

1) Add wlog_type field to well_logs table that denotes type of well log
to distinguish between simple logs (type = 0) and azimuthal and image
logs (type is chosen by user). Modify sql_well's interface accordingly.

2) Refactor add_branch_gis, get_branch_gis, add_branch_traj,
get_branch_traj implementation.

3) Call create_wlogs_table() on DB create or open in order to update DB
scheme to latest format.
sql_well: open DB via sql_well.open_db() during deserialization

Ensures that all nessessary actions are invoked (i.e. DB scheme update)
and simplifies code.
sql_well: update Python bindings

Proper overloading of member functions with multiple default parameters.
sql_well: get_wlog_names() takes wlog_type parameter (default = 0)
sql_well: remove incorrect update_branch_traj() method
common_types: fix loading of old trajectory blobs (versioning)
sql_well: don't add uid field to wells table
sql_well: fix add_branch_gis Python binding
